Suppress a few common but harmless warnings in FFX's HLSL code.
This way we don't have to modify the FSR2 shaders to get rid of these warnings.

Disable DXC shader compiler by default because enabling it for DX12 will inevitably break DX11 support.

Enabled DXC shader compiler on supported platforms, and use it to enable native 16-bit and wave operations where possible.
Moved common defines, pragmas and hacks into a new shared header file.

Use RenderTargetIdentifier magic to bind UAV outputs to SRV inputs, making obsolete the monkey patching of shaders.
Also reorganized the SRV/UAV names to match the ordering from the FSR2 source.

Don't use global_memory on PS4/5 I guess since it breaks everything

Removed #extension directives which are meant only for GLSL and which caused compiler warnings in Unity

Added some quick hacks to allow the shaders to compile for Metal.
These "interlocked" functions are not interlocked anymore now, but it's good enough for an initial test on MacOS.

Moved PSSL type definitions up, so that they apply both when FFX_HALF is defined and when not. This allows the shaders to compile for PS4/5 in both modes.
Should look into proper half-precision support; fp16 is only supported on PS4 Pro, on base PS4 everything compiles down to fp32 anyway.

Redefine HLSL globallycoherent as PSSL global_memory. The shader compiler seems to like it, and as far as I can tell it should serve the same purpose.

Initial implementation of accumulation pass. It's doing... something but it's definitely not correct yet.
Changed scene luminance into a persistent RT, since that makes it easier to control mipmaps and bind specific mip levels.

Implemented depth clip pass. Solved the problem of UAV/SRV name mismatch by monkey-patching the relevant shaders. Added default reactive mask.

Color, depth and motion vectors are now provided as regular texture inputs to the compute shaders, by blitting them from the game camera ahead of time.

Progress on managing resources. Compute luminance pyramid shader is starting to do something.
Also looked at the Lanczos LUT resource and ran into some roadblocks there.

Tweaks to make the FSR2 shaders compile on PS4/5 platforms.
FFX_HALF doesn't seem to be a thing in FSR 2.2 anymore anyway, so might as well keep that disabled.

- Implemented main FSR2 constants buffer, which now supplies the pre-exposure value to the RCAS shader.
- Converted thread groups calculation from FSR2 code

- Simplified Unity RCAS shader to basically just a few defines and a direct import of the original FSR2 shader code.
- Implemented 1x1 exposure texture and bound it to the compute shader.
- Implemented RCAS config data set with precomputed values (so we don't have to do any unsafe float-to-int conversions), apply it to a constant buffer, and made sharpness available as a slider in the inspector.

First import of Unity FSR2 test project on built-in render pipeline:
- Yoinked a bunch of code from MadGoat SSAA to build a custom render scaler
- Added a simple shader to check some of the render buffers during upscaling
- Successfully ported the RCAS compute shader from the FSR2 project into Unity!
