Refactor libyuv yuv->rgb conversion with function pointers

Use function pointers and look up tables based on RGB and
YUV image formats to call the appropriate libyuv function.

This eliminates a lot of repeated code (which can be error prone
when copy-pasting, refactoring, etc). It also makes adding new
libyuv functions simpler.

Tested with several AVIF images and the existing yuv and rgb tests
continue to pass.
