Implement HTMLOrForeignElement

Implement the interface mixin between HTML/SVG/etc as specified here:
https://html.spec.whatwg.org/multipage/dom.html#htmlorsvgelement
Note that the intention is to rename above HTMLOrSVGElement to HTMLOrForeignElement:
https://github.com/whatwg/html/issues/4702

This also removes NoncedElement.

Matches WebKit and Firefox.
