AX: Ensure that the accessibility tree is created when adding a notification
listener.

<rdar://problem/171173160>
Reviewed by Tyler Wilcock (OOPS\!).
When a layout test calls `addNotificationListener` to observe accessibility
notifications, it's possible that the accessibility tree hasn't been built
yet. If the tree doesn't exist, notifications like AXLoadComplete are never
posted, causing tests that wait for those notifications to time out.
Fix this by calling `_WKAccessibilityRootObjectForTesting` at the start of
`addNotificationListener` on both macOS and iOS. This forces the
accessibility tree to be created (if it hasn't been already) before we
begin observing, ensuring that subsequent accessibility events are properly
dispatched.
