commit fb18137422e5e4fbcb5e7e989dfe0609853f6743

CAMEL-19245: camel-java-joor-dsl - Provide the compiled classes (#9788)
## Motivation
Up to now, the only way to get the inner and anonymous classes that have
been compiled is by using reflection/introspection while it could be simplified
by adding new methods.
## Modifications:
* Add a method allowing to get all the compiled classes.
* Add some unit tests to ensure that it works as expected
