    overviewControls: Remove ControlsLayout
    
    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.
