Reviewed by Chris Fleizach and Tyler Wilcock.

Added AXObjectCache::focusedObjectForNode to handle the special cases for both focusedObjectForPage and setIsolatedTreeFocusedObject. This makes getting the focused object more consistent between ITM on and off. It will also allow to get the focused Object from the Isolated tree without hitting the main thread.
