patch 9.0.1980: win32: issues with stable python ABI
Problem: win32: issues with stable python ABI
Solution: if_python3,win32: Fix Python3 stable ABI
There were some issues in current stable ABI implementation on Windows:
* Python DLL name should be `python3.dll` instead of `python311.dll` and
so on. (See: https://docs.python.org/3/c-api/stable.html)
* Some non-stable API functions were used:
- `_PyObject_NextNotImplemented`
- `PyStdPrinter_Type`
* `reset_stdin()` and `hook_py_exit()` didn't work with `python3.dll`.
`python3.dll` is a special type of DLL called forwarder DLL.
It just forwards the functions to other DLL (e.g. `python311.dll`).
There were two issues regarding these functions:
- `python3.dll` doesn't have import tables. This caused a crash in
`get_imported_func_info()`. Add a check whether the specified DLL
has an import table.
- `reset_stdin()` and `hook_py_exit()` should be applied to the
forwarded DLL (e.g. `python311.dll`), not to `python3.dll`.
Check the export directory of `python3.dll` to find the forwarded
DLL and apply the functions to it.
