        Clone WebClipboard to be frame-specific.
        https://bugs.webkit.org/show_bug.cgi?id=53727

        For drop operations, Chrome currently snapshots the data and copies it
        into the renderer process. As we add more supported drag data types, the
        copy will become increasingly expensive. Instead, we'd like to snapshot
        data in the browser to reduce the amount of data copied and to support
        Blob in DataTransferItem. In order to allow this, we associated
        WebClipboard with a frame so it can correctly route its IPCs to the
        corresponding Chromium host.

        No new tests because no new functionality.
