LibGUI: Refactor AbstractView "multi select" mode into "selection mode"

Browse source 
There are three possible selection modes for a GUI::AbstractView.

- NoSelection
- SingleSelection
- MultiSelection

We don't enforce these modes fully yet, this patch mostly adds them in
place of the old "multi select" flag.
