Pass GrRenderTargetContext's GrColorSpaceInfo to SkShader and SkColorFilter.

Also to SkColorTo(Premul|Unpremul)GrColor4f.

This can avoid cache lookups to find GrColorSpaceXforms as the xform pointer is stored in GrColorSpaceInfo after the first lookup.

Also uses GrColorSpaceInfo to construct GrTextUtils::Paint.
