It feels weird that we need to expose this. It looks like we just need to get
screenAvailableRect(). At first, I thought this might be because this is
multiscreen aware--but I can only find two HostWindow implementations in Blink:
Chrome and PopupContainerClient.

Given that, I think it might be nicer to have screenAvailableRect() take a
Chrome* argument, and then use that to calculate the available screen rect. That
way, we don't have to expose this at all.

+mlamouri who's touched some of the WebScreenInfo stuff more recently, in case
there's something I'm missing here about multidisplay.

Done.

 
     virtual void navigate(Document& originDocument, const KURL&, bool lockBackForwardList) = 0;
     virtual void reload(ReloadPolicy, ClientRedirectPolicy) = 0;
