Implement GtkSelectionModel for GtkNotebookPages

Browse Source 
The documentation says that the model returned by
gtk_notebook_get_pages() implements the GtkSelectionModel interface, but
checking the history confirms this is a lie.

Instead of fixing the documentation, we can easily make it true, and
reduce the differences between GtkNotebook and GtkStack.

Fixes: #5837
