Implement virtual buffer dependencies (#6190)

* Implement virtual buffer copies

* Introduce TranslateAndCreateMultiBuffersPhysicalOnly, use it for copy and clear

* Rename VirtualBufferCache to VirtualRangeCache

* Fix potential issue where virtual range could exist in the cache, without a physical buffer

* Fix bug that could cause copy with negative size on CopyToDependantVirtualBuffer

* Remove virtual copy back for SyncAction

* GetData XML docs

* Make field readonly

* Fix virtual buffer modification tracking

* Remove CopyFromDependantVirtualBuffers from ExternalFlush

* Move things around a little to avoid perf impact

- Inline null check for CopyFromDependantVirtualBuffers
- Remove extra method call for SynchronizeMemoryWithVirtualCopyBack, prefer calling CopyFromDependantVirtualBuffers separately

* Fix up XML doc
