Reproducer for incorrect function argument domain type

[jwgmeligmeyling]

Reproducer that argument type is not properly resolvable from SqmFunction return type resolvers.

Test fails with:

Unexpected type ==> expected: <org.hibernate.type.CustomType> but was: <org.hibernate.metamodel.model.domain.internal.BasicTypeImpl>
Expected :org.hibernate.type.CustomType
Actual   :org.hibernate.metamodel.model.domain.internal.BasicTypeImpl

A "work around" seems to be to get the entity name and attribute name from the SqmTypedNode and look it up in the Metamodel, although this requires access to the SessionFactory which is only accessible through a deprecated method:

typeConfiguration.getSessionFactory().getMappingMetamodel()
     .getEntityDescriptor(((SqmRoot) ((SqmBasicValuedSimplePath) arguments.get(0)).getLhs()).getEntityName())
    .getPropertyType(((SqmBasicValuedSimplePath) arguments.get(0)).getNavigablePath().getLocalName());

It looks like this was already merged and fixed as part of #6780
