UML25 — Metaclass operations incomplete

The operations listed for each metaclass should give the uniqueness
and ordering of all their parameters, including return type. For
example, NamedElement::getAllNamespaces() is actually ordered. In
addition, operation redefinitions should be given, for example,
Package::mustBeOwned().

Enhance the generator to produce annotations such as ordered, nonunique for all operation parameters and
results with non-default values for isOrdered and isUnique in the generated Classifier Descriptions.
Enhance the generator to produce annotations such as redefines op() for all operation redefinitions in the
generated Classifier Descriptions.
