* 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.

Tested by:
a) Running Engine/Binaries/Linux/UnrealEditor Samples/Games/ShooterGame/ShooterGame.uproject
b) Playing game in editor
c) Running DumpGPU command in console
d) Folder pops up populated with DumpGPU html files and data plus OpenGPUDumpViewer.sh
e) Double click on OpenGPUDumpViewer.sh and GPU Viewer opens in chrome and appears to work
Also tested script on Mac by copying entire folder to Mac and executing OpenGPUDumpViewer.sh
TODO:
Better error messages when Chrome browser isn't installed
We appear to need the --allow-file-access-from-files chrome option and not sure how to get that functionality on other browsers via command line

Dumps improvements:
1) Bring up for consoles
2) Better out of memory resiliency during the dumping process
3) Dumps console variables in CSV
4) Dumps process' log after completion
5) Dumps mip chains through FDumpTextureCS compute shader
6) Dumps depth & stencil texture formats through the FDumpTextureCS compute shader
7) Dumps at draw granularity with FRDGBuilder::DumpDraw(); (experimental)
8) Dumps final png screenshot to the dump directory
9) Adds & Dumps the FRDGBufferDesc::Metadata for viewer to decode buffer binary automatically
10) Dumps the PassParameters with structure metadata to decode shader parameters automatically
11) Adds CTRL+SHIFT+/ shortcut
Viewer improvements:
1) Tips display onload to spread some knowledge to the user
2) Supports for opening any pass/resources in new web browser tab
3) Emulates 16 and 32 bits UINT texture visualization with multiple webgl 8bit UINT textures
4) Fixes the webpage's tab going out of memory after visualizing many large resources.
5) Fixes the webpage's tab going out of memory after loading large buffer.
6) Adds support for more texture format with RGB channel reswizzling
7) Implements UI color-sheme based on UE5's editor theme
8) Implements texel color picker capabable of decoding every pixel format.
9) Implements texture viewer zooming with the mouse wheel
10) Implements a r.DumpGPU.Viewer.Visualize to open a specific RDG output resource when opening the viewer
