… and SessionCreationOptions in 7.2

…lass name changed to JdbcMetadataAccessStrategy

…sionBuilderImpl and RuntimeModelCreationContext

Fixes

* return the right lock (different than ORM)
* Fix postLoad issue

…ataPojo

Hibernate ORM 7.2 now calls this method when it needs to enable
bytecode enhancements

I don't know if this test actually makes sense:
the cancel opertion happens in a different thread that causes
some error when calling session.close because the thread doesn't match
the one the session was open.

I'm going to keep it because it was introduced to solve hibernate#1436
but we might need to review it again in the future.
