DATACASS-488 - Add explicit type mappings for Name.VARCHAR and Name.TEXT.

We map varchar and text types explicitly to data types to ensure resolution to the appropriate data type if queried by name. The driver returns only text via DataType.allPrimitiveTypes() because text and varchar are aliases and allPrimitiveTypes returns a set.
