Make supported codec profiles part of each dxva_modes entry. Every DXVA2 mode is representative for a codec with a subset of supported profiles, so reflecting that in dxva_modes seems appropriate. In practice, this will more strictly check MPEG2 profiles, will stop relying on the surface format checks for selecting the correct HEVC profile, and remove the verbose messages for mismatching H264/HEVC profiles. Instead of the latter, it will now print the more nebulous "No decoder device for codec found" verbose message. This also respects AV_HWACCEL_FLAG_ALLOW_PROFILE_MISMATCH. Move the Main10 HEVC entry before the normal one to make this work better. Originally inspired by VLC's code. Merges Libav commit 70e5e7c02232d1e51c362d5572c567a9e2a8dcc2.
