Tyler Denniston df208a341b [svg] Add several skeleton classes for filters
Added:

- SkSVGFilter: This corresponds to a <filter> element. Also added some
  of the attributes of this element.
- SkSVGFe: This will be the base class of all <fe*> elements.
- SkSVGFilterContext: This will hold the contextual mapping of string id
  -> image filter result, for constructing pipelines.
