listview: Expose GtkListItemFactory APIs

Due to the many different ways to set factories, it makes sense to
expose them as custom objects.

This makes the actual APIs for the list widgets simpler, because they
can just have a regular "factory" property.

As a convenience function, gtk_list_view_new_with_factory() was added
to make this whole approach easy to use from C.
