[FFmpeg-cvslog] avformat/internal: Use forward declaration for AVCodecDescriptor

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Wed Aug  2 12:15:42 2023 +0200| [76f244b84e6ce559546a6ab46773266ace2cfb3b] | committer: Andreas Rheinhardt

avformat/internal: Use forward declaration for AVCodecDescriptor

This avoids including lavc/codec_desc.h everywhere and thereby
forces users to include it directly instead of lazily and potentially
unknowingly relying on indirect inclusions.

Also add the proper inclusion to libavformat/demux.c, one of the
two files that actually use the new field.
