Allows specifying avctx->profile with string type profile for
h264 encoders.
Private field/option "profile" may be abled to be removed for basic
h264 profiles, directly for encoders like libopenh264/h264_vaapi,
or with an map to hardware profile like h264_qsv.

One concern is some encoders have options for specific profiles,
like "high444p" for nvenc_h264 and "constrained_high" for h264_amf,
hence they may not be able to remove the private option easily.
Please help to comment.
