This will allow compressing direct to physical texture on platforms that support it
Some small RHI changes will have to be approved before turning on though

This allows us to put texture layers into physical groups that will be accessed through the same page table layer (and so must share the same UV in different physical textures).
Physical spaces can now contain multiple texture layers (one for each member of a physical group).
Changed the logic for the physical space pool descriptions so that we can support multiple texture layers. And also made the description work for Min and Max tile size values so that we don't need to specify pool sizes multiple times for each possible tile size.
Runtime virtual texture can select if it wants to use a single physical group. By default this is on so that RVT uses a single page table channel.

- FVirtualTexturePhysicalSpace* now stored using TRefCountPtr<>, since code was changed to destroy previous unused physical spaces
- Otherwise we get into bad state since AllocatedVT could reference already deleted physical space, and cause system to get out of sync and/or crash
- Also defer deletion of unreferenced physical spaces until end of each render thread update, not strictly needed, but keeps large textures from getting destroyed/recreated in some cases
