Disable accessibility notifications after each test
https://bugs.webkit.org/show_bug.cgi?id=112579

Reviewed by Tim Horton.

In WebKitTestRunner, if any tests triggered accessibility notifications,
the global notification handler would thereafter be active, and fire
notifications for all subsequent tests.

Fix by implementing AccessibilityController::resetToConsistentState() for
Mac, and using it to clear the global notification handler.

* WebKitTestRunner/InjectedBundle/AccessibilityController.cpp:
* WebKitTestRunner/InjectedBundle/mac/AccessibilityControllerMac.mm:
(WTR::AccessibilityController::addNotificationListener): Remove stupid comment.
(WTR::AccessibilityController::removeNotificationListener): Explicitly call
-stopObserving so that unregistering the observer doesn't rely on object lifetimes
(e.g. because of -autorelease).
(WTR::AccessibilityController::logAccessibilityEvents): Stub.
(WTR::AccessibilityController::resetToConsistentState): Remove the notification listener
if there is one.
* WebKitTestRunner/InjectedBundle/mac/AccessibilityNotificationHandler.h:
Add -stopObserving
* WebKitTestRunner/InjectedBundle/mac/AccessibilityNotificationHandler.mm:
(-[AccessibilityNotificationHandler dealloc]): Call -stopObserving
(-[AccessibilityNotificationHandler stopObserving]): Unregister from the notification
center.
