This is the first step towards refactoring how widgets deal with event controllers. In the future, the widget will treat controllers the same way it treats child widgets: 1. The controllers will be created without a widget. 2. There will be gtk_widget_add/remove_controller() functions to add or remove controllers. 3. The widget will hold a reference to all its controllers. This way we will ultimately be able to automate controllers with ui files.
