Because not all metadata is written as tags, the Matroska muxer
filters out the tags that are not written as tags.
Therefore the code first checks whether a Tag master element
needs to be opened for a given stream/chapter/attachment/global
metadata. If the answer turns out to be yes, it is checked again
whether a given AVDictionaryEntry is written as a tag.
This commit changes this: The Tag element is opened unconditionally
and in case it turns out that it was unneeded, it is discarded again.
This is possible because the Tag element is written into its own
dynamic buffer.

It is no longer converted since mkv_write_chapters() is called
before mkv_write_tags() which happens since commit
4ebfc13c338423cf48f1a1266c890422367f7775. Given the fact that
chapters can also be written late, mkv_write_chapters() has to
convert the metadata itself.

Before this patch the muxer writes an invalid file
(namely one in which the Projection master is a child of
the Colour element) if the following conditions are met:
a) The stream contains AVMasteringDisplayMetadata without primaries
and luminance (i.e. useless AVMasteringDisplayMetadata).
b) The stream contains AV_PKT_DATA_SPHERICAL side data.
c) All the colour elements of the stream are equal to default
(i.e. unknown).
Fortunately these conditions are very unlikely to be met.

av_dict_set() expects a different set of flags, namely the AV_DICT_*
flags. Using AV_OPT_FLAG_DECODING_PARAM (or any AV_OPT_FLAG_*) ic
av_dict_set() is therefore completely wrong and given that av_dict_set()
just doesn't care about whether the string it receives has anything
to do with a decoding parameter or not, it should just be removed
without replacement.
(The numerical value of AV_OPT_FLAG_DECODING_PARAM currently coincides
with AV_DICT_IGNORE_SUFFIX. Given that the dictionaries we are dealing
with here are always empty (i.e. NULL) before the calls to
av_dict_set(), this flag changes nothing. It would be different if
it were equal to one of the AV_DICT_DONT_STRDUP_* values.)

We can re-use any of the AV1 encoding options that will make
sense for image encoding (like bitrate, tiles, encoding speed,
etc).
The files generated by this muxer has been verified to be valid

2) Displays on Firefox (only still images, firefox does not support
animated AVIF yet).
3) Verified to be valid by Compliance Warden:

The general demuxing API uses bitstream filters to extract extradata
and the muxing API uses them in order to transform packets into
the format desired by the target format. Therefore FFStream contains
pointers to AVBSFContexts and lavf/internal.h includes lavc/bsf.h.
Yet actually, only a few files files are supposed to use these,
namely avformat.c, demux.c and mux.c. For all the other files,
it should be an opaque type that they should not touch and that
they need not know anything about. This can be achieved by not
including these headers and using the structs instead of the
corresponding typedefs.
This also forces translation units that really use the BSF API
themselves to include lavc/bsf.h directly instead of relying on
indirect inclusions (a few other files also use the BSF API;
they already abided by this).
Of course, it also avoids unnecessary rebuilds when bsf.h changes.
