Add integration live tests for Java (#660)

We add a live-test script for Java, which assembles a Maven project from
the generated code and runs it end-to-end, testing code generation
the same way as the existing live tests for C#, Go and Python.

The meta-model for problematic_keywords defines no enumerations, but
the generated Java interfaces and classes always import
``{package}.types.enums.*``. Since that package did not exist, the import
failed to resolve. We now always emit a placeholder
``NoEnumerationsDefined.java`` in ``types.enums`` so the package exists
even when the meta-model has no enumerations.

``TestDescendAndVisitorThrough`` hardcoded
``IIdentifiable``/``IReferable``, which are AAS-specific interfaces
absent from smaller test meta-models such as ``problematic_keywords``,
causing the generated test to fail to compile. We route it through
the existing generic ``Common.trace()`` helper instead, matching how
the C# generator already traces instances by their runtime type name,
so the Java generator no longer assumes anything AAS-specific.
