avformat/movenc: Add movie_timescale option to AVIF

Browse Source 
Allow specifying the movie_timescale options to AVIF ouptut.

This also makes sure that when movie_timescale is not specified,
the default value of 1000 is used instead of 0. Animated AVIF
files which don't specify the movie_timescale will have the
correct duration written in the track and movie headers after this
change (instead of writing 0).
