The canvas only needs to be saved once, per local SkSVGRenderContext.
Add a helper (saveOnce) to implement this optimization.

The method is used for clip path resolution, and is supposed to transform the path
into parent node coords -- so it should use the forward matrix, not the inverse.

Currently we use 'fill-rule' when emitting clip paths. This is wrong:
per spec [1], clip paths observe 'clip-rule', not 'fill-rule'.

The Skia SVG DOM is not a user agent, so link semantics are not
particularly interesting. But since <a> can wrap actual content, it is
important to not drop it on the floor.
The simplest thing to do is turn it into a <g> node and run with it.

In preparation of radial gradient support, move common logic into an
abstract base class (SkSVGGradient).

ClipPaths can be clipped too, e.g.:
<clipPath id="clip1" clip-path="url(#clip2)">...</clipPath>
Since we're not really drawing clips but resolving their geometry,
asPath() needs to take composed clipping into account (and intersect as
needed).

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.

Kind of a big change, to connect several new bits into something useful:
* ID tracking & lookup
* new asPaint() node virtual to support shader (and in the future filter) based paint servers
* <defs>, <linearGradient> and <stop> element support
* 'href', 'offset', 'stop-color', 'stop-opacity' attribute support
* IRI/FuncIRI and rgb(...) parsing

The main feature is <svg> viewBox and proper viewport support, but the CL
touches a few other things:
* refactor SkSVGRenderContext to auto-restore canvas state, and split the
presentation bits into a separate CoW SkSVGPresentationContext
* introduce SkSVGNode::onPrepareToRender(), as a way for nodes to push their
custom state before the actual onRender() call (instead of relying on
non-virtual SkSVGNode to know about all possible state bits)
* add a "Type" suffix to SVG types, to disambiguate (e.g. SkSVGRectType vs.
SkSVGRect)
