Kevin Lubick 5e8f45faf1 [includes] Prepare for moving SkColorSpace to forward declare
This updates all our callsites in preparation for removing
the #include "include/core/SkColorSpace.h" from SkImageInfo.h

According to go/chrome-includes [1], this will save ~150MB
(0.07%) from the compilation size. I think SkColorSpace is
a big include because it loads the skcms header, which is
big.

The follow-on CL will remove that link, once clients have
been updated as well.
