gtkmenubutton: Popup menu/popover on GtkButton:clicked

This happens on button release, which is more convenient if the gesture
can be consumed by something else (eg. window dragging), and already behaves
correctly wrt cancelled gestures, broken grabs, etc.

This also allows us to unify pointer and keyboard behavior, popping up the
menu widget in a single place.
