externals: Update fmt to 6201052

renderer_opengl: Namespace OpenGL code

externals/boost: Update to 1.68.0

Previously, we'd get warnings like:

"
c:\projects\yuzu\externals\fmt\include\fmt\format.h(2868): warning
C4127: conditional expression is constant
[C:\projects\yuzu\msvc_build\externals\dynarmic\src\dynarmic.vcxproj]
"

spamming the build output when compiling on Windows. This updates fmt to
include the upstreamed fix that silences this warning.

This updates the submodule to use 1.68.0. Notably, it gets rid of the
silly

"Info: Boost.Config is older than your compiler version - probably
nothing bad will happen - but you may wish to look for an update Boost
version. Define BOOST_CONFIG_SUPPRESS_OUTDATED_MESSAGE to suppress this
message."

message that spams the output of the build process on Windows.

config: Fixed icon size get set to 0

Namespaces all OpenGL code under the OpenGL namespace.

Prevents polluting the global namespace and allows clear distinction
between other renderers' code in the future.

qt/main: Port part of citra(#3411), open savedata works

Port #3353 from Citra: "citra-qt: Add customizable speed limit target "

maxwell_to_gl: Implement PrimitiveTopology::Lines

Port #3902 from Citra: "Add restart hotkey & menu option"

GPU: Implemented logic ops.

Used by Splatoon 2's debug menu.

logging/text_formatter: Use empty braces for initializing CONSOLE_SCREEN_BUFFER_INFO instance

Revert "Shader: Use the right sampler type in the TEX, TEXS and TLDS …"

Added missing include for pl:u

Should fix any compile errors

* Added bfttf loading

We can now load system bfttf fonts from system archives AND shared memory dumps. This allows people who have installed their system nand dumps to yuzu to automatically get shared font support. We also now don't hard code the offsets or the sizes of the shared fonts and it's all calculated for us now.

* Addressed plu fixups

* Style changes for plu

* Fixed logic error for plu and added more error checks.

- This reverts commit 3ef4b3d4.
- This commit had broken a lot of games. We really should do a full implementation of this in one change.

vfs: Replace mode.h include with forward declarations where applicable

am: Utilize std::array within PopLaunchParameter()

audio_core/filter: Add explicit cast to assignment in Process()

shader_bytecode: Parenthesize conditional expression within GetTextureType()

Resolves a -Wlogical-op-parentheses warning.

Avoids the need to rebuild these source files if the mode header
changes.

Previously this would cause warnings about implicit conversions to s16
from a double

The previous form of initializing done here is a C-ism, an empty set of
braces is sufficient for initializing (and doesn't potentially cause
missing brace warnings, given the first member of the struct is a COORD
struct).

Gets rid of the potential for C array-to-pointer decay, and also makes
pointer arithmetic to get the end of the copy range unnecessary. We can
just use std::array's begin() and end() member functions.

sdmc_factory: Remove unnecessary core include

bit_field: Convert ToBool() into explicit operator bool

Port #4056 from Citra: "Add Clear Recent Files menu action"

perf_stats: Change MAX_LAG_TIME_US to an appropriate value

25us is far too small, and would result in std::this_thread::sleep_for
being called with this as a maximum value. This means that a guest
application that produces frames instantly would only be limited to
40 kHz.

25ms is a more appropriate value, as it allows for a 60 Hz refresh
rate while providing enough slack in the negative region.

This doesn't require the central core header to be included, it just
needs the vfs headers.

Gets rid of a TODO that is long overdue.

rasterizer_interface: Remove renderer-specific ScreenInfo type from AccelerateDraw() in RasterizerInterface
