DL: Optimize PositionAndLayoutOnceIfNeeded() for display locking.

In display locking, we don't process subtrees of locked elements. In
PositionAndLayoutOnceIfNeeded, we can use this information to skip
recursing into layout code, which would abort child layout anyway.

This takes the referenced bug case from 250ms per unlock to 110ms per
unlock.
