Support domain clamping and transform matrices in YUVToRGB effects

This helps avoid flattening of YUV/A images when drawn with a strict src
rect constraint. SkiaRenderer almost always provides a strict constraint
for their YUV videos.

This adds a GM that replicates the issue in skbug:8959, and adds a GM to
the wacky_yuv set that checks domain clamping across all of the different
formats.

Bug: 8959
