Instead of a flat animator space, introduce animator groups.
This allows us to encapsulate layer animators and only dispatch ticks
when their owning layer is active.

Zero-width strokes imply hairline in Skia, but in other models (e.g.
Lottie) they are simply ignored. The latter approach avoids
discontinuities when width -> 0, so let's make it the default for sksg.

To fix gm/bigrect, needed to do adjust "largest" rect so it doesn't become empty when round-tripping with SkRect/SkIRect.
I renamed it after this.

Backpedal on node/reval-time-determined damage: nodes cannot control
the invalidation order, and shared descendants may be revalidated before
a particular ancestor gets to query their state - thus making any
decisions based on that invalid.
Instead, apply damage suppression at invalidation time, based on node
type/traits. Node types which don't generate direct damage are marked
as such, and the invalidation logic bubbles damage past them, until it
finds a valid damage receiver.
Nodes which currently suppress damage:
- PaintNode (and subclasses)
- GeometryNode (and subclasses)
- Matrix

Split the matrix component of sksg::Transform into its own, free-floating,
chainable node.
Update the composite transform animator to target matrix nodes instead of
transform nodes.
Update the layer transform attachment logic to follow "parent" references,
and build matrix inheritance chains on the fly.

Node subclasses can now control whether their bounds (changes)
contribute to damage.
Tristate:
* Default: The node bounds contribute to damage if the node itself was
invalidated, observing hasSelfInval(). This is the default
behavior.
* ForceSelf: The node bounds contribute to damage, regardless of
hasSelfInval(). Used for domain-boundary nodes (e.g. Draw),
which gate blocked fragments (e.g. geometry, paint nodes).
* BlockSelf: The node bounds do not contribute to damage, regardless of
hasSelfInval(). Used for nodes which do not contribute
damage directly (e.g. paints, geometry).

We need to discriminate between nodes whose bounds updates contribute to the dirty
region, and nodes whose bounds changes do not.
E.g. animated shape in a group: the animated shape node bounds should yield damage,
but the ancestor group bounds should not.
To accomplish this, we refine the invalidation state:
1) self invalidation == the node itself was invalidated, and its bounds updates
yield damage.
2) descendant invalidation == the node has some (self-)invalidated descendant,
but its own bounds are not contributing damage.
Also:
* hoist the bounding box invalidation logic into the base class (Node::revalidate)
and update to respect the states described above.
* remove (now-redundant) GeometryNode bbox logic.
* update revalidation methods to return the node bbox instead of void
