Introduce RenderNode::nodeAt(const SkPoint&) as the entry point for the hit-testing API.
This is backed by a onNodeAt() virtual, which gets dispatched throughout the render DAG,
and normally stops at the first leaf Draw node in encounters.
To support the implementation, introduce a GeometryNode::contains(const SkPoint&) API.
This is backed by a onContains() virtual, overridden in each concrete geometry class.
Expose nodeAt() on sksg::Scene, and add some basic unit tests.

Geometry effects (trim-path, etc) are sensitive to the SkPath conversion
direction and starting point.
Introduce SkSG{Rect,RRect) direction and initial point attributes, and
update Skottie to initialize these according to the AE model.
