[w3c/DOM-Parsing] Extended attribute [TreatNullAs] is not an attribute extended attribute (#55)

In [`interface mixin InnerHTML`][0]:

```
[CEReactions, TreatNullAs=EmptyString] attribute DOMString innerHTML;
```

In [`partial interface Element`][1]:

```
[CEReactions, TreatNullAs=EmptyString] attribute DOMString outerHTML;
```

The [`TreatNullAs` extended attribute][2] isn’t [applicable to attributes][3], it is only [applicable to types][4] (specifically [DOMString][5]).

Extended attributes appearing before the `attribute` keyword [don’t propagate to the attribute’s type][6].

These two uses of `TreatNullAs` should appear in an extended attributes list between the `attribute` and `DOMString` as [part of TypeWithExtendedAttributes][7].
