* Fix insert handling with respect to version, discriminator and generated identifier insertion
* Introduce SqmMultiTableInsertStrategy to handle multi-table inserts
* Introduce the notion of an "entity table" similar to the "id table" to handle multi-table insertions
* Implement table based and cte based multi-table insertion to support all dialects
* Implement identifier generator optimizer support for multi-table insert
* Fix validation of insert target paths against select item types
* Fix some DML validations
* Implement over-clause support in SQL AST
* Fix multi-valued filter parameter support
- Clean up Component Type, removing as many calls to its tuplizer as possible atm
- Clean up ManagedMappingType, EntityPersister, etc - mainly work around getting and setting value(s)
Still need to
- integrate embedded forms. `VirtualIdEmbeddable` does not really need it as it can use the id-mapping itself as the embedded form. But `IdClassEmbedded` should really be integrated
- integrate `VirtualKeyEmbeddable` and `VirtualKeyEmbedded` for use as inverse composite fks
- share `#finishInit` handling for `EmbeddableMappingType`, `VirtualIdEmbeddable` and `IdClassEmbeddable`
- ability to use the containing composite owner as the parent of a composite (legacy behavior is to always use the "first" entity
- clean up ComponentType, esp wrt its use of ComponentTuplizer
* Implement parameter list expansion for native queries
* Fix empty subselect fetched collection initialization
* Implement support for nested table group joins to allow joins on the map-key
* Replace `getTableReference` with `resolveTableReference` where appropriate to distinguish which calls can cause table reference joins to be created
* Fix some table reference resolving issues with inverse embeddable model parts
* Use a Fetch for entity ids instead of a DomainResult
* Fix bidirectional fetching for collection initializtion
* Implement table reference join pruning for treat usages
* Implement strict JPA compliance for different parameter styles
* Ensure From nodes in Criteria are unique
* Add unique key support to DelayedEntityFetch
* Check if FetchParent is enhanced for lazy loading for DelayedEntityFetch
* Register entity instances under all possible EntityUniqueKey
* Introduce EntityJavaTypeDescriptor that implements equality based on object identity
* Add FormatMapper for a pluggable JSON serialization and deserialization strategy
* Add native UUID type support for H2, Cockroach, PostgreSQL
* Add native INET type support for Cockroach, PostgreSQL
* Add native JSON type support for MySQL, Cockroach, PostgreSQL
* Add native INTERVAL SECOND type support for H2, Cockroach, PostgreSQL
* Add fallback JdbcTypes for new SqlTypes
* Register column types for new SqlTypes
* Add support for BasicTypeReference in TypedParameterValue
* Fix a lot of method signatures with respect to type parameter issues
* Fix CustomType, UserType and EnhancedUserType with respect to type parameters
* Get rid of StringRepresentableType and some other unused deprecated methods
