'Resolve the pending_xref *node* with the given *target*.
The reference comes from an "any" or similar role, which means that we
don\'t know the type.  Otherwise, the arguments are the same as for
:meth:`resolve_xref`.
The method must return a list (potentially empty) of tuples
``(\'domain:role\', newnode)``, where ``\'domain:role\'`` is the name of a
role that could have created the same reference, e.g. ``\'py:func\'``.
``newnode`` is what :meth:`resolve_xref` would return.
