  [Cocoa] Some AVIF images can't be rendered because their containers formats are HEIF
https://bugs.webkit.org/show_bug.cgi?id=244103

Reviewed by Myles C. Maxfield.

If the system frameworks say the image type is "public.heif", we can distingush
the case of a HEIF image from the case of an AVIF image inside a HEIF conatinver
by checking the "ftyp" box. An image is an AVIF if "avif" or "avis" is present
in the major_brand or in one of the compatible_brands of the "ftyp" box.
