csstypes: Change NTH_CHILD and NTH_LAST_CHILD change propagation

Browse Source 
For now assume that if those flags change for a node, they also changed
for all sibling nodes. This is not strictly true but simplifies
invalidation.

The reason it simplifies invalidation is that when removing or adding a
node, we can just invalidate the first node (for NTH_LAST_CHILD) and the
new node (for NTH_CHILD) and all the other nodes will be invalidated
automatically.
