manifest_xml: use Superproject to hold XML contentv2.23

Always create Superproject when there is a <superproject> tag, and have
it hold the XML content, similar to how other manifest elements are
handled.

This also adds SetQuiet and SetPrintMessages to Superproject
consistent with manifest.SetUseLocalManifests.
