d77922cc4b
Backported fixes that we already know are going to be necessary for full Unity support:
- Removed empty parantheses on GroupMemoryBarrier macro, which confuse the 2020.1 shader compiler
- Added padding field to cbFSR2 to make it exactly 128 bytes in size, which gives correct buffer alignment on iOS Metal
- Changed auto-exposure reset threshold value to 1e4f, as part of a fix for black screen flashes in OpenGL Core on Nvidia GPUs
- Clamp luma to >= 0 in auto-exposure to fix artifacting in OpenGL Core on Nvidia GPUs
- Removed #extension directives meant for GLSL, which cause shader compiler warnings in Unity

c27195fb9a
Defined a vertex/fragment shader for the accumulate pass, with initial modifications to make things compile as a proof of concept:
- Removed vk::binding directives, as they are only meant for Vulkan and don't mean anything to Unity
- Initialize inout struct as zero to stop Unity compiler complaints
- Renamed vertex main function to VertMain to prevent duplicate main function declaration
- Removed duplicate VertexOut struct declaration
- Removed unused header includes in vertex shader code, preventing duplicate declarations
- Fixed up a few relative header include paths

Reworked 2-pass FS implementation to integrate more directly with the PPV2 framework, allowing for multi-target rendering using the fullscreen triangle blit, which eliminates the need for an extra blit at the end.
Also fixed a bug where the scale factor was inverted, which caused FS upscaling output to be blurry.

Further tweaked motion vector processing, now the camera motion vectors from Unity produce an exact match with the auto-generated motion from the clip-delta matrix, in both D3D, Vulkan and OpenGL. It also makes sense with regards to the flipped Y-coordinate in screen space now. The final result looks good now too.

Empirically determined the best setup for motion vectors in OpenGL, though it still doesn't make a whole lot of sense. Added opt-in debug symbols line to the upscale shaders to make analysis easier.

Set normalized device coordinates Y direction to be up, which is standard in Unity, and properly detect non-zero motion vector inputs. This *seems* to be the correct recipe.
