Support for resources on non-contiguous GPU memory regions (#1905)

Browse source 
* Support for resources on non-contiguous GPU memory regions

* Implement MultiRange physical addresses, only used with a single range for now

* Actually use non-contiguous ranges

* GetPhysicalRegions fixes

* Documentation and remove Address property from TextureInfo

* Finish implementing GetWritableRegion

* Fix typo
