Changes QMessageBox usages to warnings, as the problems they bring to
light are being safely handled by the application and do not warrant
something of the "critical" level.

Changes LOG_CRITICAL to LOG_ERROR for the same reason. Preferring ERROR
to WARNING as yuzu is denying loading of any guest applications after
checking for these conditions.

Moved logging the GL_RENDERER string into GetUnsupportedGLExtensions()
to make more clear that unsupported extensions were already being
logged. Makes placement of the logs easier to understand later, as well.

Changes the first message to not include the OpenGL version, as the
error is caused by OpenGL failing to load.

Adds a new check for OpenGL version 4.3. This will display a message
with a similar error as well as the GL_RENDERER string. Adds a CRITICAL
log message when triggered. This prevents a crash with yuzu trying to
use older OpenGL versions.

Modifies the unsupported extension message to output the GL_RENDERER
string in the message, as well as logging the string.

Emulated mailbox presentation was causing performance issues on
Nvidia's OpenGL driver. Remove it.

Now that the GPU is initialized when video backends are initialized,
it's no longer needed to query components once the game is running: it
can be done when yuzu is booting.

This allows us to pass components between constructors and in the
process remove all Core::System references in the video backend.

The list of points is returned by const reference, so we don't need to
make a copy of every element in the list.

Due to the way Qt performs destruction of parent/child widgets, we need
to make the lifetime of the input subsystem shared across the main
window and the render window.

Abstracts most of the input mechanisms under an InputSubsystem class
that is managed by the frontends, eliminating any static constructors
and destructors. This gets rid of global accessor functions and also
allows the frontends to have a more fine-grained control over the
lifecycle of the input subsystem.

This also makes it explicit which interfaces rely on the input subsystem
instead of making it opaque in the interface functions. All that remains
to migrate over is the factories, which can be done in a separate
change.

C++20 deprecates capturing the this pointer via the '=' capture.
Instead, we replace it or extend the capture specification.

* Switch game settings to use a pointer

In order to add full per-game settings, we need to be able to tell yuzu to switch
to using either the global or game configuration. Using a pointer makes it easier
to switch.

* configuration: add new UI without changing existing funcitonality

The new UI also adds General, System, Graphics, Advanced Graphics,
and Audio tabs, but as yet they do nothing. This commit keeps yuzu
to the same functionality as originally branched.

* configuration: Rename files

These weren't included in the last commit. Now they are.

* configuration: setup global configuration checkbox

Global config checkbox now enables/disables the appropriate tabs in the game
properties dialog. The use global configuration setting is now saved to the
config, defaulting to true. This also addresses some changes requested in the PR.

* configuration: swap to per-game config memory for properties dialog

Does not set memory going in-game. Swaps to game values when opening the
properties dialog, then swaps back when closing it. Uses a `memcpy` to swap.
Also implements saving config files, limited to certain groups of configurations
so as to not risk setting unsafe configurations.

* configuration: change config interfaces to use config-specific pointers

When a game is booted, we need to be able to open the configuration dialogs
without changing the settings pointer in the game's emualtion. A new pointer
specific to just the configuration dialogs can be used to separate changes
to just those config dialogs without affecting the emulation.

* configuration: boot a game using per-game settings

Swaps values where needed to boot a game.

* configuration: user correct config during emulation

Creates a new pointer specifically for modifying the configuration while
emulation is in progress. Both the regular configuration dialog and the game
properties dialog now use the pointer Settings::config_values to focus edits to
the correct struct.

* settings: split Settings::values into two different structs

By splitting the settings into two mutually exclusive structs, it becomes easier,
as a developer, to determine how to use the Settings structs after per-game
configurations is merged. Other benefits include only duplicating the required
settings in memory.

* settings: move use_docked_mode to Controls group

`use_docked_mode` is set in the input settings and cannot be accessed from the
system settings. Grouping it with system settings causes it to be saved with
per-game settings, which may make transferring configs more difficult later on,
especially since docked mode cannot be set from within the game properties
dialog.

* configuration: Fix the other yuzu executables and a regression

In main.cpp, we have to get the title ID before the ROM is loaded, else the
renderer will reflect only the global settings and now the user's game specific
settings.

* settings: use a template to duplicate memory for each setting

Replaces the type of each variable in the Settings::Values struct with a new
class that allows basic data reading and writing. The new struct
Settings::Setting duplicates the data in memory and can manage global overrides
per each setting.

* configuration: correct add-ons config and swap settings when apropriate

Any add-ons interaction happens directly through the global values struct.
Swapping bewteen structs now also includes copying the necessary global configs
that cannot be changed nor saved in per-game settings. General and System config
menus now update based on whether it is viewing the global or per-game settings.

* settings: restore old values struct

No longer needed with the Settings::Setting class template.

* configuration: implement hierarchical game properties dialog

This sets the apropriate global or local data in each setting.

* clang format

* clang format take 2

can the docker container save this?

* address comments and style issues

* config: read and write settings with global awareness

Adds new functions to read and write settings while keeping the global state in
focus. Files now generated per-game are much smaller since often they only need
address the global state.

* settings: restore global state when necessary

Upon closing a game or the game properties dialog, we need to restore all global
settings to the original global state so that we can properly open the
configuration dialog or boot a different game.

* configuration: guard setting values incorrectly

This disables setting values while a game is running if the setting is
overwritten by a per game setting.

* config: don't write local settings in the global config

Simple guards to prevent writing the wrong settings in the wrong files.

* configuration: add comments, assume less, and clang format

No longer assumes that a disabled UI element means the global state is turned
off, instead opting to directly answer that question. Still however assumes a
game is running if it is in that state.

* configuration: fix a logic error

Should not be negated

* restore settings' global state regardless of accept/cancel

Fixes loading a properties dialog and causing the global config dialog to show
local settings.

* fix more logic errors

Fixed the frame limit would set the global setting from the game properties
dialog. Also strengthened the Settings::Setting member variables and simplified
the logic in config reading (ReadSettingGlobal).

* fix another logic error

In my efforts to guard RestoreGlobalState, I accidentally negated the IsPowered
condition.

* configure_audio: set toggle_stretched_audio to tristate

* fixed custom rtc and rng seed overwriting the global value

* clang format

* rebased

* clang format take 4

* address my own review

Basically revert unintended changes

* settings: literal instead of casting

"No need to cast, use 1U instead"
Thanks, Morph!

* Revert "settings: literal instead of casting
"

This reverts commit 95e992a87c898f3e882ffdb415bb0ef9f80f613f.

* main: fix status buttons reporting wrong settings after stop emulation

* settings: Log UseDockedMode in the Controls group

This should have happened when use_docked_mode was moved over to the controls group
internally. This just reflects this in the log.

* main: load settings if the file has a title id

In other words, don't exit if the loader has trouble getting a title id.

* use a zero

* settings: initalize resolution factor with constructor instead of casting

* Revert "settings: initalize resolution factor with constructor instead of casting"

This reverts commit 54c35ecb46a29953842614620f9b7de1aa9d5dc8.

* configure_graphics: guard device selector when Vulkan is global

Prevents the user from editing the device selector if Vulkan is the global
renderer backend. Also resets the vulkan_device variable when the users
switches back-and-forth between global and Vulkan.

* address reviewer concerns

Changes function variables to const wherever they don't need to be changed. Sets Settings::Setting to final as it should not be inherited from. Sets ConfigurationShared::use_global_text to static.

* main: load per-game settings after LoadROM

This prevents `Restart Emulation` from restoring the global settings *after* the per-game settings were applied. Thanks to BSoDGamingYT for finding this bug.

* Revert "main: load per-game settings after LoadROM"

This reverts commit 9d0d48c52d2dcf3bfb1806cc8fa7d5a271a8a804.

* main: only restore global settings when necessary

Loading the per-game settings cannot happen after the ROM is loaded, so we have to specify when to restore the global state. Again thanks to BSoD for finding the bug.

* configuration_shared: address reviewer concerns except operator overrides

Dropping operator override usage in next commit.

Co-Authored-By: LC <lioncash@users.noreply.github.com>

* settings: Drop operator overrides from Setting template

Requires using GetValue and SetValue explicitly. Also reverts a change that broke title ID formatting in the game properties dialog.

* complete rebase

* configuration_shared: translate "Use global configuration"

Uses ConfigurePerGame to do so, since its usage, at least as of now, corresponds with ConfigurationShared.

* configure_per_game: address reviewer concern

As far as I understand, it prevents the program from unnecessarily copying strings.

OpenGL macOS headers definitions clash heavily with each other

This commit aims to help easing debugging of driver crashes without
having to modify existing code.

Presentation context always has GL_DRAW_FRAMEBUFFER_BINDING as zero.
There is no need to bind the default framebuffer constantly.

According to Nsight this was using ~0.7ms per frame and it broke
renderdoc captures.

Create Vulkan instances and surfaces from the Vulkan backend.

Changes the GraphicsContext to be managed by the GPU core. This
eliminates the need for the frontends to fool around with tricky
MakeCurrent/DoneCurrent calls that are dependent on the settings (such
as async gpu option).

This also refactors out the need to use QWidget::fromWindowContainer as
that caused issues with focus and input handling. Now we use a regular
QWidget and just access the native windowHandle() directly.

Another change is removing the debug tool setting in FrameMailbox.
Instead of trying to block the frontend until a new frame is ready, the
core will now take over presentation and draw directly to the window if
the renderer detects that its hooked by NSight or RenderDoc

Lastly, since it was in the way, I removed ScopeAcquireWindowContext and
replaced it with a simple subclass in GraphicsContext that achieves the
same result

Adds a Qt and SDL2 frontend for Vulkan. It also finishes the missing
bits on Vulkan initialization.

MakeCurrent is a costly (according to Nsight's profiler it takes a tenth
of a millisecond to complete), and we don't have a reason to call it
because:
- Qt no longer signals a warning if it's not called
- yuzu no longer supports macOS

We can make this message more meaningful by indicating the location the
screenshot has been saved to. We can also log out whenever a screenshot
could not be saved (e.g. due to filesystem permissions or some other
reason).

Treating it as a u16 can result in a sign-conversion warning when
performing arithmetic with it, as u16 promotes to an int when aritmetic
is performed on it, not unsigned int.

This also makes the interface more uniform, as the layout interface now
operates on u32 across the board.

This class contains non-trivial members, so we should default the
destructor's definition within the cpp file.

Same thing (for platforms we support), less reading.

This function is defined as taking an int, not a bool.

We can just pass a pointer to GMainWindow directly and make it a
requirement of the interface. This makes the interface a little safer,
since this would technically otherwise allow any random QWidget to be
the parent of a render window, downcasting it to GMainWindow (which is
undefined behavior).

We can just invoke these functions by qualifying the object name before
the function.
