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).
