[svg] Add SkSVGProperty class for presentation attributes
This CL adds a new SkSVGProperty<T,B> class and uses it instead of
SkTLazy for the presentation attributes. Ideally this will form the
foundation for improvements to our presentation attribute parsing
as well as correctness for inherited/non-inherited properties.
