Bug 892246 - Allow subdocument scrolling to reveal margins. r=kats, a=lsblakk

This adds a notification callback to PanZoomTarget that the PanZoomController

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.
