This commit fixes an issue where not all 4 results of tld4 were being
written, the color component was defaulted to red, among other things.
It also implements the bindless variant.

externals: Track upstream opus

video_core: Implement texture format E5B9G9R9_SHAREDEXP.

Kernel: Implement a New Thread Scheduler V2

This commit implements the E5B9G9R9 Texture format into the general 
system and OpenGL backend.

maxwell_3d: Silence implicit conversion warnings

While we are at it, unify types for dirty reg pointers.

astc: Silence implicit conversion warnings

Implement Fast BRX, fix TXQ and addapt the Shader Cache for it

shader_ir: Use std::array with std::pair instead of std::unordered_map

Shader_Ir: Fix TLD4S from using a component mask.

Shader_IR: allow lookup of texture samplers within the shader_ir for instructions that don't provide it

VideoCore: Unify const buffer accessing along engines and provide ConstBufferLocker class to shaders.

Revert "ci: Add build name to archive root folder"

This reverts commit 5e553a6c.

shader_bytecode: Make Matcher constexpr capable

Greatly shrinks the amount of generated code for GetDecodeTable().

Collapses an assembly output of 9000+ lines down to ~3621 with Clang,
and 6513 down to ~2616 with GCC, given it's now allowed to construct all
the entries as a sequence of constant data.

Given the overall size of the maps are very small, we can use arrays of
pairs here instead of always heap allocating a new map every time the
functions are called. Given the small size of the maps, the difference
in container lookups are negligible, especially given the entries are
already sorted.

video_core/shader: Resolve instances of variable shadowing

Silences a few -Wshadow warnings.

Tracks upstream opus, allowing the library to be easily updated. While
we're at it, we incorporate the CMakeLists.txt so that we have easy
control over the requirements of the build.

ci: Add build name to archive root folder

hid/npad: Minor cleanup

shader_ir/memory: Ignore global memory when tracking fails

gl_shader_decompiler/vk_shader_decompiler: Resolve implicit fallthrough cases

TLD4S always outputs 4 values, the previous code checked a component 
mask and omitted those values that weren't part of it. This commit 
corrects that and makes sure all 4 values are set.

Ignore global memory operations instead of invoking undefined behaviour
when constant buffer tracking fails and we are blasting through asserts,
ignore the operation.

In the case of LDG this means filling the destination registers with
zeroes; for STG this means ignore the instruction as a whole.

The default behaviour is still to abort execution on failure.
