        Add Support to WebCore to optionally call a platform-specific gesture recognizer
        https://bugs.webkit.org/show_bug.cgi?id=49345

        Added an ability for the EventHandler to invoke an optional platform
        specific gesture recognizer.

        No tests added because the change should be functionally invisible.
