Primary Key Ordering with Hibernate >6.4

[novakfrobert]

Hibernate 6.4 added the capability to order primary key columns by defining a Unique Index containing all the PK columns. See this hibernate issue and the relevant Hibernate PR.

• hibernate/hibernate-orm@b431029

I think liquibase-hibernate can make use of this by updating the PrimaryKeySnapshot.

From:
hibernatePrimaryKey.getColumns()

To:
hibernatePrimaryKey.getOrderingUniqueKey().getColumns()

That way we can order primary keys via an annotated java model and have liquibase accurately report differences, ie: if the primary key is out of order.
