GSoC'24: Implement pybind11 for bindings

[blueloveTH]

Project goal

• Implement a pybind11 compatible solution to pocketpy as an alternative way to create bindings for c++ functions and classes
• Support binding use cases for the Cave Engine

Application guide: https://pocketpy.dev/gsoc/guide/

Project mentors

@blueloveTH & @UnidayStudio

Details (The first stage)

We have provided a set of test cases in the following repo.

https://github.com/pocketpy/pkpy_with_pybind11

You need to:

1. Develop pybind11 headers via meta template programming based on c++17
2. Pass all test cases provided by @UnidayStudio
