ControlsLayout is a tiny layout manager whose only purpose is emit "allocation-changed" after allocation. This signal was listened to update the workspaces actual geometry. However, since d66cd0d2067a, ControlsManager doesn't listen to this signal anymore, rendering the class useless. Remove ControlsLayout.
