[NO ISSUE][EXT] Java UDF framework refactoring

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
1. Separated the JObjects and its subtypes.
2. Add JBuiltinTypes so we don't have to create an object to get JType.
3. Dead code removal.
4. Memory usage optimization in JRecord Serialization.
5. Several fixes about incomplete type implementations in Java UDF and
getting JObjects in UDF examples.
