This was previously used to wrap the COM proxy for the document child of an OOP iframe in a content process. It was returned by OuterDocAccessible::LocalChildAt*. Instead, BrowserBridgeChild now directly holds the COM proxy and MsaaAccessible traversal methods have specific code paths to return that as appropriate. Since we no longer need the Windows OuterDocAccessible traversal overrides for OOP iframes nor remote top level documents, they have been removed entirely.
