Add support for parsing AVIF still images. This patches supports
AVIF still images that have exactly 1 item (i.e.) no alpha channel.
Essentially, we will have to parse the "iloc" box and populate
the mov index.

With this patch, we can decode still AVIF images like so:
ffmpeg -i image.avif image.png

Partially fixes trac ticket #7621

LGTM

Will push tomorrow if no one else has.

Can you provide a sample AVIF image and command that this patch allows decoding of?

I tried a couple of samples from Netflix[1] and MS[2] and none worked, even with forcing MOV demuxer ("moov atom not found" or "error reading header").
