REVISION SUMMARY
  This patch ports the Bluetooth applet to use `Kirigami.PlaceholderMessage`. In the
  process, and as a necessary precondition, it also refactors the code to be more
  declarative.

TEST PLAN
  Everything still works perfectly and there are no visual changes aside from the message
  having the same margins etc as all the other ones now: F8254152: vokoscreenNG-2020-04-22_15-02-49.webm <https://phabricator.kde.org/F8254152>
