Spring Migrate orm.hibernate5 to orm.jpa.hibernate package for Hibernate ORM 7.0

Our orm.hibernate5 package is outdated and in unclear state: It used to work with Hibernate ORM 5.x only but in Spring Framework 6.x we also tolerated its use against Hibernate ORM 6.x (with a few tweaks).

As of Spring Framework 7.0 and Hibernate ORM 7.0, we cannot support our outdated HibernateTemplate at all anymore (due to the underlying query facility having been removed in Hibernate itself). At the same time, there is still a need for some native Hibernate support classes but ideally tightly integrated with JPA and HibernateJpaVendorAdapter. In order to share some delegates with HibernateJpaVendorAdapter (without circular package dependencies), those classes should live under orm.jpa.hibernate instead which also removes the misleading version number from the package name.

Specifically, the following classes will be provided in org.springframework.orm.jpa.hibernate for use with Hibernate ORM 7.0: - LocalSessionFactoryBuilder - LocalSessionFactoryBean - HibernateTransactionManager - HibernateExceptionTranslator - SpringBeanContainer - SpringSessionContext

Those classes are useful for use with JPA-based repositories as well as Hibernate-native repositories based on SessionFactory.getCurrentSession(), and not least of it all for a mix of both. An existing orm.hibernate5 based setup can easily be migrated to use the orm.jpa.hibernate setup classes while the repositories would keep using SessionFactory.getCurrentSession() from an injected SessionFactory instance, without any changes necessary for the repository implementations themselves. For any remaining HibernateTemplate-based repositories, the recommendation is to migrate to SessionFactory.getCurrentSession().
