Fix 4:4:4 RGB software rendering. Use new libyuv matrix funcs.

libyuv now has matrix functions which lets us greatly simplify
our PaintCanvasVideoRenderer code. They don't have a identity
matrix though for GBR content, so use libyuv::MergeARGBPlane
for 4:4:4 RGB content (gbr/bt709/iec61966_2_1).

These fixes allow us to pass new four-colors.mp4 rendering
tests for the WebCodecs pipeline.

This also exposed a bug where we were missing color spaces on
wrapped video frames.
