Port from gtk::TreeView to non-deprecated gtk::ListView or gtk::ColumnView via gtk::TreeListModel

FWIW I was going to do this with the original GTK4 release but I've held off on this intentionally. I'm on my phone so I don't have a link to it ready, but long story short there is a rather nasty problem with ListViews in that scrolling often breaks with 200+ items.
I'd love to move away from these widgets since they're deprecated, but I've already seen some issues this causes having moved the completion popup over to using it and I'd very much like to hold off until ListView is actually stable. It's a bit of a shame that they're trying to deprecate the TreeView when it's replacement isn't actually ready for use in half of the cases it's been used for traditionally, but I've been told they're going to try fixing this before releasing GTK5.

(the next time I sit down at a computer and go through all of the Github issues I will actually put a proper link to the gitlab issue for the GTK bug I'm talking about, just for reference)

That makes sense, thanks. I just noticed that it was using GtkTreeView here and remembered that getting deprecated some weeks ago :)

JFYI - recently I believe that the scrolling bug blocking this has finally been fixed, so I'm going to drop the upstream label from this :)
