avformat/matroska{dec, enc}: Parse BlockAdditionMapping elements
Adds handling of dvcC/dvvC block addition mappings.
The parsing creates AVDOVIDecoderConfigurationRecord side data.
The configuration block is written when muxing into Matroska,
if DOVI side data is present for the track.
Most of the Matroska element parsing is based on Plex's FFmpeg source code.
