Add usage of SkYUVAIndex as pre-step to transfer to new YUVA API
The plan foward is to have a new API on SkImage to make from YUVA
textures which a combination of array of textures and array of
SkYUVAIndex struct indicating which texture and channel to read for
each plane. This is a pre-step to let the old API use these ideas.
