Florin Malita e932d4b3a9 [SVGDom] Add fill-rule support
There's a bit of friction with this attribute, because per spec it is
an inherited presentation attribute, but in Skia it is part of the
actual SkPath state.

So we must add some plumbing to SkSVGShape & friends to allow overriding
the fill type at render-time.
