Fix T71611: Outliner - Show only Visible/Hidden Objects not working when hiding Collections

Use BASE_VISIBLE_VIEWLAYER (rather than BASE_VISIBLE_DEPSGRAPH -- which
is not including the 'Hide in Viewport')

Note: the is one case where this still 'fails':
- 'Show only Hidden' plus excluding the parent collection (would be nice
to show those -- but contents of excluded excluded collections dont get
show in any case... this would be more work and for another report...)
