demux_mkv: remove ancient codec mapping leftovers
All of this is basically due to how MPlayer's codecs.conf worked. It had a demuxer-interface based an AVI, using FourCCs and data structures found in AVI. FourCCs were used to map streams to decoders. For codecs not supported by AVI, "MPlayer internal" FourCCs were made up. codec_tags.c is there to bridge demuxers written against the old API to the mpv one. By now, only demux_mkv.c needs this (because demux_mkv is the only serious demuxer left - preferably, we should use libavformat for mkv too, but I can't see this happening any time soon, because libavformat _still_ doesn't support segment linking). But the codec tables are full of weird stuff automatically extracted from the old codecs.conf tables. Most of it isn't needed for mkv. Remove all custom tags, readd those used by demux_mkv.c internally (see vinfo and mkv_audio_tag tables). The rest is handled by the tables provided by libavformat, which includes AVI and QT tags.

-/* The following tables map FourCCs to codec names (as defined by libavcodec).
- * However, this includes only names that are not defined by libavformat's
- * RIFF tag tables, or which are mapped differently (for unknown reasons).
- * These mappings were extracted from the codecs.conf file when it was removed,
- * and these mappings have been maintained for years, meaning they are well
- * tested and possibly make some files work. Or they could just be bugs.
- *
- * Note that demux_lavf does not use these tables, and always uses the native
- * libavformat mappings.
- *
- * Note about internal mplayer FourCCs:
- *
- * These are made-up FourCCs which don't actually show up in files, but which
- * were used by the original MPlayer to identify codecs. Since we don't quite
- * know/care if there are still some uses of them left, they're still here.
