Add initial set of hibernate 7.0 metadata (#579)

* Add initial set of hibernate 7.0 metadata (still old format)

Hibernate 7 is still in beta, still if there's a need to early test integration this is a least some metadata that allows to bootstrap hibernate.

* Add tests to capture AnnotationDescriptor handling

* Update test to match what hibernate does internally

* fix formatting errors

* fix metadata errors only reported by ci - sigh

* one has slipped

* Add update hibernate-core default-for entry.

Make sure hibernate 6.6.x versions are routed to the 6.6 metadata.

* Remove generated resources & update comments.
