This struct contains the pressed/latched/locked set of modifiers applying to the event, and may be filled in by backends generating those events. Other places where we forward modified key events, state may be normally obtained from the original event. Since this constructor is used in a variety of places, this commit updates them all in one go. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3369>
