ea7375c9e9 avformat/avisynth: move avs_planes* consts into relevant function
These consts are only used in the switch(planar) case located in
avisynth_create_stream_video and nowhere else in the demuxer,
so move them into that function directly.

48d6cd35a2 avformat/avisynth: remove library allocation from global state
As part of this, the mutexes are no longer necessary, and
avisynth_read_close needs to check that avs->avs_library.library
still exists before it attempts to call avisynth_context_destroy
and dlclose.

c0fddbae79 avformat/avisynth: remove atexit() handler
The atexit() handler in the avisynth demuxer was added because
there was a conflict in AvxSynth that arose due to their use
of C++ global objects, particularly in relation to having
added a logging function relying on log4cpp.

This conflict was responsible for causing a segfault on exit.
It did not affect Windows with the (at the time) upstream
AviSynth 2.5 and 2.6, nor does it affect AviSynth+.

Unfortunately, none of this was actually shielded by ifdefs
indicating the fact it was only needed for AvxSynth, so four
years ago when AviSynth+ replaced AvxSynth as the handler
for AviSynth scripts on Unix-like OSes, the fact that the
atexit handler was no longer necessary was overlooked.

49a6e448d7 avformat/movenc: use stream indexes when generating track ids
In some scenarios nb_tracks isn't the same as nb_streams, so a given id may end
up being used for two separate streams.

e.g. when muxing an IAMF track followed by a video track, if the IAMF track
consists of several streams, the video track would end up having an id of 2,
which may also be used by one of the IAMF streams.
