Get rid of custom bindings for V8NodeList

Get rid of custom bindings for V8NodeList

Get rid of custom bindings for V8NodeList by generating visitDOMWrapper() and
adding an ownerNode() method to the NodeList class. This method calls
LiveNodeList::ownerNode() if the NodeList is live, and returns null otherwise.

There is no web-exposed change in behavior.

For reference, the generated code looks like:
void V8NodeList::visitDOMWrapper(void* object, const v8::Persistent<v8::Object>&
wrapper, v8::Isolate* isolate)
{
    NodeList* impl = fromInternalPointer(object);
    if (Node* owner = impl->ownerNode()) {
        setObjectGroup(V8GCController::opaqueRootForGC(owner, isolate), wrapper,
isolate);
        return;
    }
    setObjectGroup(object, wrapper, isolate);
}
