Right now, the private contexts of every decoder supporting
H.274 film grain synthesis (namely H.264, HEVC and VVC)
contain a H274FilmGrainDatabase; said structure is very large
700442B before this commit) and takes up the overwhelming
majority of said contexts: Removing it reduces sizeof(H264Context)
by 92.88%, sizeof(HEVCContext) by 97.78% and sizeof(VVCContext)
by 99.86%. This is especially important for H.264 and HEVC
when using frame-threading.
The content of said film grain database does not depend on
any input parameter; it is shareable between all its users and
could be hardcoded in the binary (but isn't, because it is so huge).
This commit adds a database with static storage duration to h274.c
and uses it instead of the elements in the private contexts above.
It is still lazily initialized as-needed; a mutex is used
for the necessary synchronization. An alternative would be to use
an AV_ONCE to initialize the whole database either in the decoders'
init function (which would be wasteful given that most videos
don't use film grain synthesis) or in ff_h274_apply_film_grain().

Add a separator line to show_filters() function output to maintain
consistent formatting with other show functions like show_codecs,
show_formats_devices, etc. This provides uniform formatting across
all command-line output functions for better readability and
parsing by external tools.
To avoid pulling in the entire libavfilter when using the DSP functions
from checkasm.
The rest of the struct is not needed outside vf_idet.c and was moved there.

Due to the recent id3v2 refactor, FLAC was left out due to
earlier code not checking for id3v2 presence on FLAC.
Without the id3v2 data parsed, detection of FLAC and therefore
demuxing fails.

There's very little performance difference vs SSE2/SSSE3 and most
systems will use the AVX2 implementations anyway.
This reduces code size and compilation time by a significant amount.
It has already been done in init.

Modify the read/write function could use udp socket.
There are more patches to make dtls really work.

Depending on the threading backend the stdlib uses, creating a
mutex/condvar can be quite expensive.
So keep this object alive in the ctx, on which we synchronize via the
uninit mutex anyway.
