[issue45474] [C API] marshal.h must not use FILE* type in the limited C API

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

Include/marshal.h defines 2 functions with FILE* argument in the limited C API, whereas the PEP 384 disallows that:

"In addition, functions expecting FILE* are not part of the ABI, to avoid depending on a specific version of the Microsoft C runtime DLL on Windows."
https://www.python.org/dev/peps/pep-0384/

PyAPI_FUNC(void) PyMarshal_WriteLongToFile(long, FILE *, int);
PyAPI_FUNC(void) PyMarshal_WriteObjectToFile(PyObject *, FILE *, int);

I propose to exclude these functions from the limited C API.

Hopefully, they are not part of the documented stable ABI.
