ShadowRoot.cloneNode() must always throw a DATA_CLONE_ERR exception.

https://bugs.webkit.org/show_bug.cgi?id=91704 Reviewed by Dimitri Glazkov. Source/WebCore: According to the spec, ShadowRoot.cloneNode() should throw a DATA_CLONE_ERR exception. The existing implementation returned null object instead. We change the cloneNode() interface so that we can throw an exception from cloneNode().
