[evolution] EMailDisplay: Remove bind_iframe_content_visibility().

    EMailDisplay: Remove bind_iframe_content_visibility().
    
    None of my attachment samples invoke bind_iframe_content_visibility().
    Both it and toggle_widget_visibility() appear to dead code.  Removing
    the functions causes no ill side-effects as far as I can tell.
