Add a private API that lets widget opt-in to animated updates of the adjustment value. When enabled, all calls to gtk_adjustment_set_value will smoothly transition from the old value to the new value, using a fixed easing function and a configurable duration. The animation is tied to the frame clock of the widget. By implementing this in GtkAdjustment, we can enable animation for both scrollbars and keybindings, which are often implemented in the child widget of the scrolled window. https://bugzilla.gnome.org/show_bug.cgi?id=732376
