Mario Kart World draws some of its geometry with NVN task and mesh programs
(the task program culls and writes the mesh workgroup count and a payload
to its stage buffer; each mesh workgroup reads it back and writes vertices
and primitives). Add Task and Mesh stages and translate them for
VK_EXT_mesh_shader:
- the ISBE pseudo instruction from the lowering becomes reads and writes
of an emulated stage buffer: the task's output region is the task
payload, the mesh output regions live in workgroup memory
- every EXIT of these stages jumps to one final return, so all
invocations reach the epilogue: a barrier, then OpEmitMeshTasksEXT, or
OpSetMeshOutputsEXT and a copy of the 32-element vertex and primitive
groups (lines named by the mesh header's and the pass-through geometry
header's output maps) to arrayed and per-primitive outputs
- Sirit lacks the two mesh instructions: they are emitted as OpStore
markers and replaced after assembly
- fragment inputs a mesh program writes per primitive get PerPrimitiveEXT
The captured task and mesh programs of the title translate to SPIR-V that
spirv-val accepts.

An experimental approach to introduce an smarter way to use and access QUAD's capabilities on shaders, suggested by @gidoly some months ago, finally came into something usable; current implementation checks GLASM, GLSL and Vulkan on their own way, stablishes proper emitters and receivers for Quads inside our recompiler, which are the introductions for future changes; checks for support and actual feature bit, OpCodes and mask were added within this PR. Meanwhile the expected behavior was to reduce graphical issues (on games with Quad shaders reliant), we encountered a very slight performance increase depending on what game and shader are actually compiled.

that included opcodes.h (#4180)
small oopsie; we dont need 6 copies of the same 22KB table
(removes 5*22 = 110 KB worth of redundant stuff)
this also enforces static on the types defined in the header so they arent memoized into a non-inlined value (aka. compiler just grabs value instead of well, yknow, assuming its a constant area)

Mostly fixing unused *, implicit conversion, braced scalar init,
fpermissive, and some others.
Some Clang errors likely remain in video_core, and std::ranges is still
a pertinent issue in shader_recompiler
shader_recompiler: cmake: Force bracket depth to 1024 on Clang
Increases the maximum fold expression depth
thread_worker: Include condition_variable
Don't use list initializers in control flow
