[whatwg] Window::showModalDialog() missing [Variadic]

[Cameron McCormack]

The >1 argument version of Window::showModalDialog() is missing a
[Variadic] on the second argument:

  interface Window {
    …
    any showModalDialog(in DOMString url);
    any showModalDialog(in DOMString url, in any arguments);
    …
  };

Since no arguments need be passed for those designated with [Variadic],
the two operations could just be combined into one:

  interface Window {
    …
    any showModalDialog(in DOMString url, [Variadic] in any arguments);
    …
  };
