Deprecation: aiida.orm.nodes.data.upf and verdi data core.upf (#6114

)

The `UpfData` data plugin and related utilities have been replaced by
the versions maintained in the `aiida-pseudo` plugin. The latter has now
been significantly adopted by most users and plugin in the ecosystem, so
the outdated original version in `aiida-core` can be deprecated and
removed.
