ManagePasswordBubbleView wants to monitor events on a specific window,
currently using aura specific code that won't work for MacViews.
views::EventMonitor is enhanced to support monitoring events on a window,
with both Mac and Aura implementations.

Also includes minor compile fixes in ZoomBubbleView and StatusBubbleView.
