feat: xlang homogeneous collection serialization between java/python (#2130)
## What does this PR do?
This PR implements homogeneous xlang collection serialization between
java/python. Changes include:
- Xlang homogeneous collection serialization in cython/python
- Xlang chunk map serialization in pure python for debug
- Use homogeneous collection serialization in java
- homogeneous collection serialization between java and python
## Related issues
Closes #2131
Closes #2132
