  Serialize WebCore::Color instead of NSColor, UIColor, and CGColorRef in AttributedStrings

Reviewed by Brady Eidson.

NSAttributedStrings generated by WebKit and PDFs can have colors as attributes.  We need to keep the
CGColorRefs and UIColor/NSColors separate so the NSAttributedStrings have the same attribute types on
both sides of IPC, but we should serialize them as a WebCore::Color instead of a RetainPtr so we can
work towards removing RetainPtr serialization.
