Revert of Lots of progress switching to SkColorSpace rather than SkColorProfileType (patchset #10 id:180001 of https://codereview.chromium.org/2069173002/ )

Reason for revert:
Mac crashes in GrUploadPixmapToTexture

Original issue's description:
> Lots of progress on switching to SkColorSpace rather than SkColorProfileType
>
> Fixed a bunch of code in Ganesh, as well as usage of SkColorProfileType in most of our tools (DM, SampleApp, Viewer, nanobench, skiaserve, HelloWorld).
