Message : D3D11: Split off DXGI component type query. This query is currently a part of a std::map. Split it off to its own switch using auto-generation based on the format string. Also introduce a DXGI-to-angle format map. This map is not totally complete because some more esoteric formats don't have corresponding ANGLE formats yet. We should add these other formats (EG NV12) if we need them.
