Reviewed by Ryosuke Niwa.

When constructing a document in XMLHttpRequest::responseXML(), we would fail to pass
the TextDecoder we used on the new document (unlike what we do in the HTML parser).
This means that Document::characterSet() would not be able to determine the encoding
our decoder used and would always return UTF-8.
