texture_cache: Test format compatibility before copying

Browse source 
Avoid illegal copies. This intercepts the last step of a copy to avoid
generating validation errors or corrupting the driver on some instances.

We can create views and emit copies accordingly in future commits and
remove this last-step validation.
