[gnome-control-center] applications: Add shortcuts permissions

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 64283554360efac98c89a1840921476196940878

    applications: Add shortcuts permissions
    
    gnome-shell saves the user choice for applications allowed to disable
    regular shortcuts in the permission store, using "GRANTED" or "DENIED"
    (in gnome-shell/js/ui/inhibitShortcutsDialog.js).
    
    Add a new entry to change that permission in the application panel,
    similar to what gnome-shell does.
