Add a new configuration option typeSuffix and typePrefix to the CodeGenConfig class and update the code generation methods to append the affixes to the generated type names.

* **CodeGenConfig**: Add a new configuration option `typeSuffix` and `typePrefix` to the `CodeGenConfig` class.
* **Java DataTypeGenerator**: Update the `generate` method to append the `typeSuffix` and `typePrefix` to the generated type names.
* **Kotlin DataTypeGenerator**: Update the `generate` method to append the `typeSuffix` and `typePrefix` to the generated type names.
