Outliner visibility: Respect original viewport enable/disable state

Note: We still change it to the collection we are directly isolating/making
visible and its parents (in the case of isolating). But no longer its children.

Feedback and discussion on D4011. The motivation is that if we don't keep those
locked the disable state becomes useless.
