    passwordPage: make latin kbd layout (en) available for password entries
    
    If the current keyboard layout is not a latin one we will add the
    fallback kbd layout 'en'. This calls out to gnome-shell where the
    logic to detect the keyboard layout is kept. The layout will be
    available in the popup switcher and the taskbar keyboard layout
    switcher.
    
    (Rebase 3.38: Fix minor rebase conflicts.)
