D3D12: use one barrier to transit states for all subresources

If a texture's old states of all subresources are the same, and its
new states are the same too, then we can use one barrier to transit
states for all subresources. We don't need to use one barrier per
each subresource.

This change can reduce barriers we dispatched, in order to improve
performance for particular situations.
