[sksg] More inval fixes

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
