Original change's description:
> [includes] Remove include link between SkPathRef.h and SkRRect.h
>
> According to go/chrome-includes [1], this will save about
> 40MB (0.02%) off the Chrome build. http://screen/4GnPjFaYpwCVHVL
>
> I'm not quite sure why the link is so expensive, but we can
> forward declare it and move the implementation from the .h
> to the .cpp file easily enough.
