Users are PresShell::GetRootWindow, and PresShell::EventHandler::HandleEvent

Used mainly to for event retargeting to parent PresShell.

Change to use BrowsingContext.

If parent is out-of-process DocShell, then forward event handling via IPC.

Kannan says replacing nsIDocShellTreeItem calls should block enabling Fission in Nightly (M6).
