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.
