Add hypersistence-utils-hibernate-63 module for Hibernate 6.3

[tmvlpl]

These changes should make the code compatible with Hibernate 6.3 and fix #657.

Details:

• As suggested in the issue discussion I have removed the PostgreSQLEnumType and deprecated it in the other Hibernate 6 modules.
• The abstract base classes MutableType and DescriptorImmutableType now implement DomainType<T> instead of SqmExpressible<T>. It looks to me as though DomainType is a kind of SqmExpressible default implementation but I am a bit confused by all the different type interface hierarchies.
• The explicit cast in the BindArrayTypeQueryParameterTest seems to be necessary, as i could find no way to register the custom function return type with the hibernate sqm.
• I have updated the optional/test dependency versions in the new module and aligned them with the SpringBoot 3.2 BOM.

Thanks, I'll review it when I have some time.

Does it make sense to support 6.3 since hibernate already dropped support? Maybe go straight to 6.4?

And since @Type(PostgreSQLEnumType.class is removed now, does it make sense to mention the migration to something like @JdbcType(PostgreSQLEnumJdbcType.class)? Or is that something that should stay in the documentation of Hibernate?

@tmvlpl I'll squash the commits and merge it if the tests run fine.

The tests run fine on Hibernate 6.3, but they fail on 6.4. Since 6.3 is no longer maintained, I think that it will be useful to make it work on 6.4 as well.

@tmvlpl I'll merge this PR and create a new issue for 6.4.

Fixed.

However, while the tests will work on Hibernate 6.3, they will not work on 6.4 because Hibernate keeps on changing the Type contract.

If you will need to have the Types work on Hibernate 6.4, you will need to fix #685
