dart:html: Add Element.removeAttribute

- Improve `element.attributes.remove(name)` to compile to `element.removeAttribute(name)`.
- Improve `element.getNamespacedAttributes(namespace).remove(name)` to compile to
  `element.removeAttributeNS(namespace, name)`.
- Add removeAttribute[NS].
- Add hasAttriute[NS].
- Assert attribute names are not null to prevent conversion to "null"/"undefined".
- TODO: Assert values are not null to prevent conversion to "null"/"undefined".
- namespaceURI does not need checking since null and undefined map to 'no namespace'.
