9021ffbb95 Build Python modules as CMake MODULEs (#3259) 
Python since 3.8 no longer links to the interpreter library, so
symbols like `PyExc_AttributeError` will be undefined at link time.

This causes build failures when shared libraries are linked with
`-Wl,--no-undefined`. Use `TYPE MODULE` for python extension modules,
which allows to specify distinct flags via CMAKE_MODULE_LINKER_FLAGS
vs CMAKE_SHARED_LINKER_FLAGS. (The same is already used by
`pybind11_add_module(... MODULE ...)`).

Fixes #3258.

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
