ffmpeg | branch: master | Haihao Xiang <haihao.xiang at intel.com> | Mon Dec 13 14:50:35 2021 +0800| [50c38e1a4453f8073b980e91b336e7d94e65769a] | committer: Zhong Li

lavc/qsvenc: define profile array per codec

The SDK defines HEVC, VP9 and AV1 profiles in the same values
e.g.
MFX_PROFILE_HEVC_MAIN             =1,
MFX_PROFILE_VP9_0                 =1,
MFX_PROFILE_AV1_MAIN              =1,

To avoid potential errors when adding VP9, AV1 profiles later,
this patch defines profile array per codec.
