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.
