Improvements to accessibility extension api support for "views":

1. Handles the new wrench menu.
2. Uses NotifyAccessibilityEvent to find out when focus changes, rather
     than installing focus change listeners that need to be cleaned up.

BUG=none
TEST=Updated AccessibilityEventRouterViewsTest.TestFocusNotification
