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.

+In a few places existing code assumes that uint32_t == unsigned int.

+'unsigned long', the original code fails to build.

+Subject: [PATCH 03/10] reuse wasm_assets.py for generating an archive of
+ python lib dir
+
+wasm_assets.py is a useful script to prepare the smallest possible
+package of pre-compiled python stdlib modules. There is very little
+wasm-specific there.
+
+This patch adds nuttx to the supported OS list in the script, as well
+as fixes what I think is a bug in path calculation.

+Subject: [PATCH 05/10] gh-122907: Fix Builds Without HAVE_DYNAMIC_LOADING Set
+ (gh-122952)
+
+As of 529a160 (gh-118204), building with HAVE_DYNAMIC_LOADING stopped working.
This is a minimal fix just to get builds working again. There are actually a
number of long-standing deficiencies with HAVE_DYNAMIC_LOADING builds that need
to be resolved separately.
