0466c9f6bf python: remove __init__.py 
now you'll need to always use a wheel package
avoid some issue when trying to run venv from root dir
e.g. `./build/python/venv/bin/python -c "from ortools.pdlp import solve_log_pb2"`

c7441c346c cmake: Migrate to Python3 and use Development.Module 
note: Development.Module is use to look for python header only
since library is not available on manylinux.
see: https://gitlab.kitware.com/cmake/cmake/-/issues/20425

note2: Development.Module has been introduced in CMake 3.18
