Refreshes the AccessibilityNode.frame of all nodes in the accessibility hierarchy.
This is a convenience method that updates the AccessibilityNode.frame of all nodes in the
accessibility hierarchy (based on AccessibilityNode.frameGetter) and notifies the screen
reader of these updates by calling IAccessibilityNotificationDispatcher.SendLayoutChanged
(with a null parameter).
Call this method when most or all of the nodes on the screen require a layout update. For example, when the
user scrolls the application's interface, or when the orientation of the screen changes.
