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.

Working SGSR2 2-pass FS implementation, bit dirty but good enough for testing.

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.

More specifically, set NDC Y-coordinate to be up when the Unity graphics API has UV's starting at the top

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.

Consolidated SGSR2 shaders into single .compute files as there's not much point in using includes, and grouped them together into a 3-pass folder. This will make it easier to add the other variants later.
