dzn: Provide a helper to check if 2 formats are compatible

D3D12 supports fomat casting through optional features. Let's
add a helper to query whether 2 formats are compatible or not.
The compatibility depends on the formats+usage pair
(CopyTextureRegion() is less strict than the texture sampling
logic).
