This CL adds a type enum to SkSVGIRI that will eventually be used to
distinguish between local fragments ('#frag-id'), non-local fragments
('/path/to/file.png') and data URIs ('data:image/png;base64,...').
To do so required a bit of refactoring of other types that previously
treated IRIs as basic strings. There are no functional changes in this
CL.
