Use XMLDictSerializer for resource extensions.

Patches around bug 852141 by using the XMLDictSerializer instead of
the ExtensionsXMLSerializer for XML serialization of resource
extensions.  This will allow XML to be emitted, but does not correct
the underlying problem: many existing resource extensions do not
have defined XML serializers.  (Additionally, existing serializers,
including ExtensionsXMLSerializer, should be converted to
templates.)
