Notify BrowserAccessibilityManager of frame info after already loaded
BrowserAccessibilityManager is not notified that frame info is ready
when accessibility wasn't turned on when the frame info was updated in
ContentViewCore. As a result, calls to getAccessibilityNodeProvider()
will not return the node information of the page in this situation.
This arrises when accessibility is turned on after the page was loaded,
such as by UIAutomator. Because BrowserAccessibility is initialized
asynchronously, there is no guarantee that it will complete in time for
the call to getAccessibilityNodeProvider. However, experiments have
shown that many smaller pages (very common for WebView applications)
return accessibility node information successfully after this change.
