Ensure changed status of all referenced paint properties are cleared
Previously in the following case: Transform tree: Root t1 t2 Clip tree: Root c1 (localTransformSpace=t1) c2 (localTransformSpace=t2) Paint chunk: (t2, c2, e0) after a document lifecycle update, t1's changed status was left not cleared, causing DCHECK failure if the next document update just needed repaint (which requires no changed status of all referenced paint properties). Now when clearing changed status, for clip and effect nodes, also clear LocalTransformSpace and OutputClip (for effect). To avoid the cost of repeated walking along the same tree paths, use cleared_sequence_number_ to indicate which nodes have been cleared.
