strip down SkICC.cpp

Most of SkICC{.h,.cpp} is unused and gone.

I've renamed the part that's left to SkWriteICCProfile() and tweaked its
API just a little, leaving SkICC:WriteToICC() a wrapper around it.

Most of the tests in ICCTest.cpp are moot and deleted, but a few looked
somewhat valuable so I've kept them with a little modification.
