Gets all of these types and interfaces out of the global namespace.

* Port #4013 from Citra: "Init logging sooner so we dont miss some logs on startup"

* Fix compilation

* Added GetBootMode

Used by homebrew

* Added enum for GetBootMode

gl_rasterizer_cache: Several improvements

gl_rasterizer: Implement partial color clear, stencil clear, and stencil test.

- Used by Splatoon 2.

 gl_shader_gen: Use a std::vector to represent program code instead of std::array

gl_shader_decompiler: Implement LOP3

* Swap "Plus" with "Minus" on the controller GUI

Major fix /s

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.

Prevents implicit conversions.

While convenient as a std::array, it's also quite a large set of data as
well (32KB). It being an array also means data cannot be std::moved. Any
situation where the code is being set or relocated means that a full
copy of that 32KB data must be done.

If we use a std::vector we do need to allocate on the heap, however, it
does allow us to std::move the data we have within the std::vector into
another std::vector instance, eliminating the need to always copy the
program data (as std::move in this case would just transfer the pointers
and bare necessities over to the new vector instance).

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
