This allows retrieving the code object of a function using `function.__code__`, and then reconstructing a function from a code object using `FunctionType(code_object)`. This feature is controlled by `MICROPY_PY_FUNCTION_ATTRS_CODE` and is enabled at the full-features level. Signed-off-by: Damien George <damien@micropython.org>
