python: Make it compatible with python3.12
Python 3.12 removes distutils so it's mandatory to use setuptools with python >= 3.12.
This patch prints a message when trying to run the setup.py script with a python >= 3.12 without setuptools and try to use the setuptools import by default.
This patch also creates a new file, pyproject.toml [1], to prepare for building in modern systems.
