interpreters/python: Add Python's port to NuttX
This is the NuttX's port of Python (cpython)! Initial support of Python includes building the Python's static library and the `python` (Programs/python.c) application. Python's modules are stored in `pyc` (byte-code file) and loaded as needed from flash.
