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.

cpu_interrupt_handler: Mark move contructor/assignment as deleted

ipc_helpers: Remove usage of the global system instance

Resolves numerous deprecation warnings throughout the codebase due to
inclusion of this header. Now building core should be significantly less
noisy (and also relying on less global state).

This also uncovered quite a few modules that were relying on indirect
includes, which have also been fixed.

The interrupt handler contains a std::atomic_bool, which isn't copyable
or movable, so the special move member functions will always be deleted,
despite being defaulted.

This can resolve warnings on clang and GCC.

video_core: dma_pusher: Remove integrity check on command lists.

externals: Update fmt to 7.1.2

Updates to the latest bugfix release of fmt.

settings: log value of CPU_Accuracy

- This seems to cause softlocks in Breath of the Wild.

core: Remove usage of unicorn

common/fiber: Move all member variables into impl class

Hides all of the implementation details for users of the class. This has
the benefit of reducing includes and also making the fiber classes
movable again.

General: Fix clang build

settings: Simplify initializer of resolution factor

This can use a braced initializer to accomplish the same thing with less
code.

shader: Partially implement texture cube array shadow

Allows building on clang to work again

core/settings: Move configuring_global behind an API

General: Resolve a few missing initializer warnings

Rather than have directly modified global state here, we can make it an
implementation detail and have an interface that changes are queried
through.

Improvements to GPU synchronization & various refactoring

Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.

This also allows us to remove our dependency on Python.

nvdec: Make use of [[nodiscard]] where applicable

microprofile: Silence warning in headers

Silences a truncation warning by making the truncation explicit and
documenting the reason for it.

common: Enable warnings as errors

hle: service: ldr: Implement UnloadNrr.

Cleans up common so that we can enable warnings as errors.

Prevents bugs from occurring where the results of a function are
accidentally discarded

async_shaders: Increase Async worker thread count for >8 thread cpus

- Refactor so that SubmitGPFIFO and KickoffPB use shared functionality.
- Implement add_wait and add_increment flags.

- Log corrupted command lists, rather than crash.
