Crash in RenderMenuList::didUpdateActiveOption.

Reviewed by Chris Fleizach.

Source/WebCore:

Enabled test accessibility/menu-list-sends-change-notification.html.

- Check the type of the AccessibilityObject before downcasting in RenderMenuList.
- Fixed handling of the AXMenuListValueChanged notification on the Mac.
This notification was previously ignored and hence the LayoutTest was failing.
