DX12: Improve buffer copy tracking for DXR replay #2525
Description
PR #2523 improved copy tracking for DXR replay when the same buffer region is copied to multiple times within the same DXR command list. However, for copies to buffers that are referenced indirectly (e.g., if a count buffer is used for execute indirect or DispatchRaysDesc buffer of ExecuteIndirect(DispatchRays)) there needs to be additional tracking.
