Additional validation of texture copies (#7935)

* Additional validation of texture copies

 * Copies must not overlap.
 * Copies of multisampled or depth/stencil formats must span
   the entire texture.
 * Move no-op for zero-size copies after parameter validation.

Closes #2951
Fixes #7844

* Fix issue with combined depth+stencil copy on dx12

* PR feedback
