[gnome-control-center/mwleeds/region-login-screen-toggle] region: replace the "Login Screen" button

[Robert Ancell <rancell src gnome org>]

commit 945a1ccb0985c08a019583f09292c22a74427437
Author: Felipe Erias Morandeira <femorandeira igalia com>

    region: replace the "Login Screen" button
    
    ...on the title bar with joined toggles (like in Background panel) for a
    clearer UI.
    
    Note 2020-08-26: This patch has been in Endless OS since 2014. It seems
      like a good UX change, so I'm proposing it upstream with some minor
      changes. - mwleeds
