AX: With ENABLE_LOCAL_FRAME, focused node API is not traversing iframe
boundary

Reviewed by Joshua Hoffman.
Based on a patch originally started by Tyler.
Each frame has its own AXObjectCache and isolated tree, and only the
focused frame's own cache handles its focus change, so an ancestor
tree (including the main frame's, which VoiceOver queries) was never
pointed at a focused descendant local frame. Point each ancestor local
frame's isolated-tree focused object at the AXLocalFrame leading
toward the focused subframe (focusedObjectForLocalFrame /
localFrameLeadingToFocusedFrame / updateAncestorFramesFocusedObject),
and have AXIsolatedObject::focusedUIElementInAnyLocalFrame() descend
that chain to the real focused element.
