Serialize attribute nodes as the empty string (#36875)

The existing code asserts that attribute nodes are never serialized.
This is wrong, because you can pass an attribute node to
`XMLSerializer::serializeToString`. Instead, the spec mandates that
these are serialized as empty strings
(https://w3c.github.io/DOM-Parsing/#dfn-xml-serialization-algorithm).

Testing: Includes a new web platform test
Fixes: https://github.com/servo/servo/issues/36872
