python: Can't reopen .pyc file

The issue is caused by _Py_fopen() being used as though it can deal with paths encoded in FS-default encoding (UTF-8 by default on Windows), but in fact it's just a simple wrapper around fopen() from the C runtime, so it uses the current ANSI code page, breaking if PYTHONLEGACYWINDOWSFSENCODING is not enabled.

I could find only two callers if _Py_fopen() on Windows:

* https://github.com/python/cpython/blob/db68544122f5/Python/pythonrun.c#L380 (which caused this issue)

* https://github.com/python/cpython/blob/db68544122f5/Python/errors.c#L1708

PyErr_ProgramText() doesn't seem to be called in CPython, but https://github.com/python/cpython/blob/db68544122f5/Include/pyerrors.h#L243 claims that filename is "decoded from the filesystem encoding", which doesn't match the code.
