HHH-18228: Fix hibernate-tool code generation (ClassNotFoundException)

[fanste]

Foreign keys based on compound keys run into a check for java records. But the to-be-generated classes do not exist on the classpath and therefore the check fails.

Hibernate doesn't seem to be dead... So the project is simply not interested in community contributions?! Would be too sad, if no solution will be implemented for that problem...

Reproducer: https://github.com/fanste/reproducers/tree/hhh-18228

Run it using the command mvn generate-sources.

This should throw the following error:

[ERROR] Failed to execute goal org.hibernate.tool:hibernate-tools-maven:6.6.2.Final:hbm2java (entity-generation) on project hhh-18228: Execution entity-generation of goal org.hibernate.tool:hibernate-tools-maven:6.6.2.Final:hbm2java failed: component class not found: Tbltest1Id

Reason is the compound primary key of tblTest1 also used as a foreign key in tblTest2. The demonstrated use case is simplied to the bare minimum.
