chrg6 ca5e5eb5a4 Add AMD FSR 3.1 upscaling, and run DLSS's smaller modes on a 16:9 picture too. ...

The Upscaling choice gains FSR 3.1 Native AA, Quality, Balanced, Performance and Ultra Performance. FSR 3.1 runs
through AMD's signed amd_fidelityfx_vk.dll (loaded at run time; the build kit ships it) in DLSS's place, on the same
scene light, depth and camera motion vectors and at the same render scales. Its Vulkan back end needs
VK_KHR_get_memory_requirements2, which the device now enables when FSR 3.1 is chosen.

A half-size effect pass with three targets and a half-size depth was taken for a G-buffer, which switched every later
frame to the deferred frame shape: there the output pass of a smaller scene was never found, so DLSS Quality,
Balanced, Performance and Ultra Performance did nothing on a 16:9 picture. Such a pass smaller than the scene is now
left alone.
