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.
