[gtksourceview/wip/chergert/gsv-gtk4: 162/192] completion: track changes to shortcut activation




commit fe9bdaec0b36cba62bf948e8bb86ae6c8a6faa19

    completion: track changes to shortcut activation
    
    There will be further followup work here, but one of the big side-effects
    is that we'll have to redesign event propagation for completion. It might
    make sense to just overhaul completion at the same time given how much
    the end APIs will change from things like:
    
     - Window placement with new GDK APIs
     - Icon changes from GTK icon theme
     - Shortcut and keyboard activation
     - List model usage for reduced overhead
     - Removal of treeview
