Introduce sksg::BlendModeEffect and use to wrap Skottie layers based on
their "bm" property.
Depending on the presence of non-trivial layer blend modes and the nature
of the destination buffer (fully transparent vs. unknown/pre-filled), we
may now need to render animation frames into a separate layer for correct
compositing.
Track the presence of non-trivial layer blend modes such that we only incur
this extra layer overhead when needed. Also allow clients to pass a "drawing
to fully transparent buffer" hint such that we can avoid the extra layer even
when blend modes are present.

Generalize sksg::TintColorFilter into GradientColorfilter, to support

Keep the two-color/single-matrix (tint) specialization, and use a table
color filter for the general case.

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.

Image filters cannot let descendent damage pass through, as they may
transform their inputs arbitrarily.
Introduce the notion of "damage override" SG nodes (nodes which block
descendent damage and replace it with their own), and update
ImageFilterEffect to opt in for this behavior.
Also make InvalidationController damage dispatch optional (such that we
don't accumulate inval rects unnecessarily).

ScopedRenderContext tries really hard to avoid unnecessary RenderContext
initializations.
This is most likely unneeded because
a) the structure is quite lightweight
and
b) all ScopedRenderContext instantiation sites imediately call setters
which require a writable context (assuming no-op args are uncommon)
Let's get rid of that over-engineered gunk.

sice that's what's actually in it.
