NV_transform_feedback, NV_transform_feedback2 and
ARB_transform_feedback3 with NV_transform_feedback interactions allows
implementing transform feedbacks as dynamic state.

Maxwell implements transform feedbacks as dynamic state, so using these
extensions with TransformFeedbackStreamAttribsNV allows us to properly
emulate transform feedbacks without having to recompile shaders when the
state changes.

gl_device: Avoid devices with CAVEAT_SUPPORT on ASTC

hid: Stub GetXpadIDs

glsl: Squash constant buffers into a single SSBO when we hit the limit

shader/other: Fix hardcoded value in S2R INVOCATION_INFO

maxwell_to_vk: Add R16UI image format

- Used by Octopath Traveler

buffer_cache: Avoid copying twice on certain cases

maxwell_3d: Initialize more registers to their expected value

format_lookup_table: Implement G24S8 format as S8Z24

fixed_pipeline_state,gl_rasterizer: Swap negative viewport checks for front faces

Allows Minecraft: Nintendo Switch Edition (a.k.a. old Minecraft) to boot and go ingame

This avoids using Nvidia's ASTC decoder on OpenGL.
The last time it was profiled, it was slower than yuzu's decoder.

While we are at it, fix a bug in the texture cache when native ASTC is
not supported.

Avoids compilation errors at the cost of shader build times and runtime
performance when a game hits the limit of uniform buffers we can use.

vk_rasterizer: Implement constant attributes 

OpenGL: Enable Debug Context and Synchronous debugging when graphics debugging is enabled

texture_cache: Optimize GetSurfacesInRegion

gl_device: Enable compute shaders for Intel proprietary drivers

Previously we were disabling compute shaders on Intel's proprietary driver due to broken compute. This has been fixed in the latest Intel drivers. Re-enable compute for Intel proprietary drivers and remove the check for broken compute.

shader/other: Implement MEMBAR.CTS

Geometry shaders built from Nvidia's compiler check for bits[16:23] to
be less than or equal to 0 with VSETP to default to a "safe" value of
0x8000'0000 (safe from hardware's perspective). To avoid hitting this
path in the shader, return 0x00ff'0000 from S2R INVOCATION_INFO.

This seems to be the maximum number of vertices a geometry shader can
emit in a primitive.

Add xbyak external

maxwell_3d: Reduce severity of logs that can be spammed

texture_cache: Implement depth stencil texture swizzles

patch_manager: Add support for case-sensitivity on Linux

These logs were killing performance on some games when they were
spammed. Reduce them to Debug severity.

gl_shader_manager: Unbind GLSL program when binding a host pipeline

Changes many patch_manager functions to use a case-less variant of
GetSubdirectory. Fixes patches not showing up on *nix systems when
patch directories are named with odd cases, i.e. `exeFS'.

main: Log host system memory parameters

Avoid copying to a staging buffer on non-granular memory addresses.
Add a callable argument to StreamBufferUpload to be able to copy to the
staging buffer directly from ReadBlockUnsafe.

maxwell_to_vk: Add format B8G8R8A8_SRGB and add Attachable capability for B8G8R8A8_UNORM

This avoids most heap allocations when collecting surfaces into a
vector.
