Checks if AVIF can encode image.

This method tries to create an AVIF image and save it to disk via imageavif(). If that fails, it's likely a codec missing, or the function was disabled. This is an expensive operation to run, so we cache its result.

Return value

bool TRUE if AVIF is fully supported, FALSE otherwise.
