Tyler Denniston a0a5146ba9 [svg] Use new parsing for gradient classes
- Added new SVG_OPTIONAL_ATTR macro for lazy properties
- Added SkSVGIRI type -- we need explicit types now to be able to
  dispatch via the templated parse function
- Converted several attribute parse functions to templated version
