Most of the lines here are the result of running iwyu to get the right
includes after removing all the offending includes. A few constants need
to be had from the C api instead of the C++ API to make this work. The
SkParagraphTest and SkParagraphImpl are still using C++ API with
icu::UnicodeString, which will be cleaned up later.
