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.
