Move id attribute to parent Element interface

Move id attribute to parent Element interface

Move id attribute from SVGElement / HTMLElement to their Element parent
interface to match the latest DOM specification and avoid duplication:
http://dom.spec.whatwg.org/#dom-element-id

This behavior is consistent with Firefox.

There is no web-exposed behavior change because we haven't moved
properties from instances to their prototype, as per the Web IDL
specification (http://dev.w3.org/2006/webapi/WebIDL/#es-attributes).

Given that getIdAttribute() is already defined in Element.h, this change sounds
reasonable. LGTM.

IE10, however, still exposes 'id' on the HTMLElement / SVGElement prototype.
