[FFmpeg-cvslog] avcodec/msmpeg4dec: Move setting decode_mb for WMV2 to wmv2dec.c

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Wed Oct 26 01:26:32 2022 +0200| [ca96456c0e77fa93b295363344fc943ae0fa61ec] | committer: Andreas Rheinhardt

avcodec/msmpeg4dec: Move setting decode_mb for WMV2 to wmv2dec.c

It avoids checks and allows to make ff_wmv2_decode_mb() static;
furthermore, it allows to avoid a config_components.h inclusion.
