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 --------- Co-authored-by: riperiperi <rhy3756547@hotmail.com>
