Reland "[graphite] Use colorspace matrix to handle RGB swizzle."

This is a reland of Ia4f0cd9e64e28a33c16a5b8b0928c38db7a63d6c

Original change's description:
> Handles the swizzle swaps by manipulating the gamut matrix.
> * BGR is a column swap
> * RRR puts the sum of the matrix rows in the left component
> * 000 zeros out the matrix
>
> Alpha swizzle is handled prior to this. If the alpha changes it
> will either be R or 1, which is handled by multiplying by a 2-vector.
