Hardware S2R special registers match gl_Thread*MaskNV. We can trivially
implement these using Nvidia's extension on OpenGL or naively stubbing
them with the ARB instructions to match. This might cause issues if the
host device warp size doesn't match Nvidia's. That said, this is
unlikely on proper shaders.

hid: Clear keyboard states & fix logic issue

FS: Improve emulation of device saves

nv_flinger: Use enum for pixel format instead of u32

DmaPusher: Remove dead code in step

vk_rasterizer: Match OpenGL's FlushAndInvalidate behavior

Match OpenGL's behavior. This can fix or simplify bisecting issues on
Vulkan.

Frontend: Remove tracking for context wrapper

audio_renderer: Better voice mixing and 6 channel downmixing

Improve time zone support

shader_ir: Add separate instructions for ordered and unordered comparisons and fix NE on GLSL

Previously we never cleared the states of the entries and the key would stay held down, also looping over the key bytes for each key lead to setting every bit for the key state instead of the key we wanted

vk_graphics_pipeline: Implement rasterizer_enable on Vulkan

Stub hid:SendKeyboardLockKeyEvent

Supersedes #3738 and #3321

Needed for Puchikon 4 SmileBASIC 1.0.0

CI: Don't check clang format on early access builds

"Not equal" operators on GLSL seem to behave as unordered when we expect
an ordered comparison.

Manually emulate this checking for LGE values (numbers, not-NaNs).

externals: Cmake version checks

texture: Implement R8G8UI
