Outliner: Make restriction icons inactive based on hierarchy value

If the parent of a collection has a setting disabled, the children should have
that setting inactive.

In some cases a column may affect another one. For example, disabling a
collection to render should make holdout and and indirect only inactive.

In View Layer it works for both objects and collections.
For Scenes mode, it works only for collections.
