HDR data is clipped in AVIF images

Reviewed by Simon Fraser.
This implements a temporary fix for rendering images with HDR data on macOS. The
system libraries on macOS BigSur and Ventura do a smooth conversion for the HDR
to SDR if the destination is a CGBitmapContext. This workaround will be used to
fix this problem by drawing the HDR image to a temporary local CGBitmapContext
before drawing it to the destination context.
