class XmlEncoder in Drupal 8

Adds XML support for serializer.

This acts as a wrapper class for Symfony's XmlEncoder so that it is not implementing NormalizationAwareInterface, and can be normalized externally.

@internal This encoder should not be used directly. Rather, use the `serializer` service.
