Local Collections: Allow users to show hidden collections

Users now can turn on in a viewport collections that are temporarily
hidden (eye) in the view layer.

Design task: T61327

As for the implementation, I had to decouple the visibility in the
depsgraph from the visibility in the view layer.

Also there is a "bug" that in a way was there before which is some
operators (e.g., writing a text inside of a text object, tab into edit
mode) run regardless of the visibility of the active object. The bug was
present already (with object type visibility restriction) in 2.80 so if
we decide to tackle it, can be done separately (I have a patch for it
though P1132).
