LibGUI/AbstractView: Remove on_selection

Browse source 
Since the introduction of multi-select, we have had both `on_selection`
and `on_selection_change`, the latter of which was only invoked when a
change in selection came in through the model.

This removes `AbstractView::on_selection` and replaces it usage with
the more explicit `on_selection_change` everywhere.
