Allow binding prefix to empty namespace URI when serializing

During parsing a prefix couldn't be bound to "no namespace", but it's
possible to get into that state through DOM mutation. The spec[1] has
language to handle it, so attempt implement that.

Firefox-only Failures

  • /domparsing/XMLSerializer-serializeToString.html [wpt.fyi]
    • Check if the prefix of an attribute is replaced with a generated one in a case where the prefix is already mapped to a different namespace URI.: FAIL
    • Check if attribute serialization takes into account of the same prefix declared in an ancestor element: FAIL
    • Check if start tag serialization applied the original prefix even if it is declared in an ancestor element.: FAIL
    • Check if generated prefixes match to "ns${index}".: FAIL
    • Check if no special handling for XLink namespace unlike HTML serializer.: FAIL

    • Check if an attribute with namespace and no prefix is serialized with the nearest-declared prefix even if the prefix is assigned to another namespace.: FAIL (Chrome: FAIL, Safari: FAIL)
    • Check if the prefix of an attribute is NOT preserved in a case where neither its prefix nor its namespace URI is not already used.: FAIL (Chrome: FAIL, Safari: FAIL)
    • Check if the prefix of an attribute is replaced with a generated one in a case where the prefix is already mapped to a different namespace URI.: FAIL (Chrome: PASS, Safari: PASS)

    • Check if attribute serialization takes into account of the same prefix declared in an ancestor element: FAIL (Chrome: PASS, Safari: PASS)
