This adds a notification callback to PanZoomTarget that the PanZoomController can call to notify GeckoLayerClient that a subdocument is being scrolled. This allows GeckoLayerClient to call LayerMarginsAnimator and alter the margins accordingly, stopping a page from trapping the toolbar on/off the screen with a screen-covering subframe.
