Add gtk_widget_prepend_controller

Add a variant of gtk_widget_add_controller that
inserts the controller at the beginning, instead
of the end. This will be used in entry completion
to make sure the entry completion key event handling
supersedes the entry one while the popup is open.

Keep this private for now, until we determine if
it needs to be public api.
