jason hoerner 0fb10e3017 MGPU: Fixes for Lumen, solving issues with black or too dark lighting on secondary GPUs or when swapping GPU assignments for a view. ...

* Page captures are now tracked separately per GPU, to avoid problems with uninitialized pages on other GPUs.  Pages that need capturing for the first time on a given GPU are prioritized and not counted against the throttled limit for page recaptures.
* Lumen scene buffer uploads are run across all GPUs.
* Lumen one-time procedural texture generation (OctahedralSolidAngleTexture) runs across all GPUs.
* DumpGPU was upgraded to be able to preview compressed formats used by Lumen (BC4, BC5, BC6H, BC7), critical for debugging Lumen behavior.
