tests/fate/libavutil: add FATE test for ambient_viewing_environment

Browse Source 
Test av_ambient_viewing_environment_alloc with and without the size
out-parameter, and av_ambient_viewing_environment_create_side_data.
Verifies the {0, 1} rational defaults set by get_defaults(),
write/read-back of the three AVRational fields, frame side data
attachment, and OOM paths via av_max_alloc.
