        anyPageIsProcessingUserGesture is not longer needed because user gesture state is static
        https://bugs.webkit.org/show_bug.cgi?id=62601

        Previously, our user-gesture state was per-frame.  Code needed to check
        the "global" user gesture state called anyPageIsProcessingUserGesture()
        to iterate through all the frames and look for one that was processing
        a user gesture.  Since we changed the user gesture state to be static,
        iterating over every frame in existence isn't needed.

        This patch also cleans up a couple other user-gesture callsites I saw
        while I was in this code.  Code should just call
        ScriptController::processingUserGesture directly instead of
        trampolining through other functions.
