Build both Python 2 and Python 3 bindings If both Python 2 and Python 3 are found, then build bindings for both of them during the build process. Currently, one version of Python is detected automatically, and building for the other requires changes the CMake config. The largest chunk of this change generalizes OpenCVDetectPython.cmake to find both a Python 2 and Python 3 version of Python. Secondly, the opencv_python module is split into two modules, opencv_python2 and opencv_python3. Both are built from the same source. but for different versions of Python.

Merge pull request #20611 from VadimLevin:dev/vlevin/pure-python-modules * feat: OpenCV extension with pure Python modules * feat: cv2 is now a Python package instead of extension module Python package cv2 now can handle both Python and C extension modules properly without additional "subfolders" like "_extra_py_code". * feat: can call native function from its reimplementation in Python
