avformat/movenc: Add loop parameter to animated AVIF
The HEIF specification permits specifying the looping behavior of
animated sequences by using the EditList (elst) box. The track
duration will be set to the total duration of all the loops (or
infinite) and the duration of a single loop will be set in the edit
list box.
The default behavior is to loop infinitely.
Compliance verification:
* This was added in libavif recently [1] and the files produced by
ffmpeg after this change have EditList boxes similar to the ones
produced by libavif (and avifdec is able to parse the loop count as
intended).
* ComplianceWarden is ok with the produced files.
* Chrome is able to play back the produced files.
