REVISION SUMMARY
  Our keyboard layout kcm allows to set a global shortcut to switch to a
  specific keyboard layout. So far KWin/Wayland did not support those
  shortcuts, only the switch to next layout shortcut was supported.
  
  This change introduces support for custom layout shortcuts. For that
  we iterate over all available layouts and check whether a shortcut is
  registered. If that is the case a QAction is created and passed to
  KGlobalAccel.
  
  As the triggering code is similar to the menu, the switchLayout lambda
  is split out into a dedicated method and translating the layouts is
  extracted into a method.
