  [AVIF Downlevels] Allow pixi property to be missing in AVIF images
https://bugs.webkit.org/show_bug.cgi?id=270180

Reviewed by Cameron McCormack.

If an image is missing the pixi property, decoding its frames will fail because
we enable AVIF_STRICT_PIXI_REQUIRED when avifDecoder is created. So we need to
remove this restriction to be compatible with newer OSs and other browsers.
