Unify entity and any discriminator handling

Description

At the moment, Hibernate is using a mix of new and legacy descriptors for mapping entity discriminators. The legacy contracts include:

  • org.hibernate.persister.entity.DiscriminatorMetadata

  • org.hibernate.persister.entity.DiscriminatorType

  • org.hibernate.type.MetaType

The corresponding new runtime mapping contract is:

  • org.hibernate.metamodel.mapping.EntityDiscriminatorMapping

  • org.hibernate.metamodel.mapping.internal.AnyDiscriminatorPart

Much of the consolidation happens through the shared converter - org.hibernate.metamodel.mapping.DiscriminatorConverter

This is done as much as currently possible as a grouping of work. I’ll do some more work on this under and a lot more opportunity opens up as we work through the changes to building the metamodel
