avformat/movenc: look for the Intra profile flag before assuming a stream is AVC-Intra
Fixes issue #20018.
Note that Codec Descriptors are not written for all these ai** codec tags, and no
considerations were ever made to ensure parameter sets are present in muxed packets.
Their usage may result in unplayable files if parameter sets are only available
in extradata (Default behavior for x264 encoding when combined with this muxer).
