D3D12 created initial states don't need to be copied

* This would require proper barriers and special handling for e.g. readback
  resources, and the only time we create initial states is when the resource was
  created mid-frame (since all pre-frame resources are dirty, so would have
  initial states prepared). That means it's zero initialised, so our zero-
  initialised created state is fine.
