Implement parsing and writing of SPS,PPS,VPS,PH,AUD,SEI and slices.
Add ff_cbs_type_h266 to cbs types tables and AV_CODEC_ID_H266
to cbs codec ids.

* take num_ticks_per_picture_minus_1 into account, since that is a part
of the framerate computation
* stop exporting num_ticks_per_picture_minus_1 into
AVCodecContext.ticks_per_frame, as that field is used for other
purposes (in conjunction with repeat_pict, which is not used at all by
av1)
Avoid compiling error if included by multiple sources.

The only encoders avaliable using mediacodec were h264 and hevc. This
patch adds the vp9 encoder.

This patch add another ARIB caption decoder using libaribcaption
external library.
Unlike libaribb24, it supports 3 types of subtitle outputs:
* text: plain text
* ass: ASS formatted text
* bitmap: bitmap image
Default subtitle type is ass as same as libaribb24.
Advantages compared with libaribb24 on ASS subtitle are:
* Subtitle positioning.
* Multi-rect subtitle: some captions are displayed at different
position at a time.
* More stability and reproducibility.
To compile with this feature:
* libaribcaption external library has to be pre-installed.
https://github.com/xqq/libaribcaption
* configure with `--enable-libaribcaption` option.
`--enable-libaribb24` and `--enable-libaribcaption` options are
not exclusive. If both enabled, libaribcaption precedes as
order listed in `libavcodec/allcodecs.c`.

Currently, several components select atsc_a53, despite
not using anything from it themselves. They only select
it because parsing SEI messages adds an indirect dependency.
But using direct dependencies is more natural, so add
dedicated subsystems for them.
It already allows to remove a superfluous dependency of
the HEVC QSV encoder on hevc_sei and atsc_a53.
Adding new subsystems only becomes effective after a reconfiguration.
In order to force this, some needed headers (which are only included
implicitly before this commit) were included explicitly in
libavformat/allformats.c.

This is in preparation for splitting VC-1 from msmpeg4.
(msmpeg4data.c was originally intended to be just this;
9488b966c7 changed it).

The encoder seems to be trading blows with hevc_nvenc.
In terms of quality at low bitrate cbr settings, it seems to
outperform it even. It produces fewer artifacts and the ones it
does produce are less jarring to my perception.
At higher bitrates I had a hard time finding differences between
the two encoders in terms of subjective visual quality.
Using the 'slow' preset, av1_nvenc outperformed hevc_nvenc in terms
of encoding speed by 75% to 100% while performing above tests.
Needless to say, it always massively outperformed h264_nvenc in terms
of quality for a given bitrate, while also being slightly faster.
It is only used by metasound.c, so this allows to make
the data static.
To do this, remove metasound_data.h, rename metasound_data.c
into metasound_data.h (and add inclusion guards, remove ff_
prefixes etc.).
