c3186302bd Add skcms directory to public includes
skcms is part of Skia's public API now. This attempts to recognize that,
and pave the way for moving the header to another location more easily
in a follow up CL, or - at a minimum - for clients that redistribute
Skia as a library + includes to relocate the skcms.h header as part of
that.

18df87ec8b Fix bugs and add features to imgcvt
- The dst_profile data needs to live at least as long as the profile.
- Support converting jpg sources (where pixmap alpha type is kOpaque).
- Add a fallback path that makes the destination profile usable.

fd731e4684 add a few more ways to convert images to imgcvt
Interestingly, the draw ends up a little different than the
writePixels() and skcms paths.  Maybe just premul/unpremul?
