[issue46584] Modernize `ctypes/test_python_api` by removing old version check

[Nikita Sobolev]

New submission from Nikita Sobolev <mail at sobolevn.me>:

Right now Lib/ctypes/test/test_python_api.py has these lines:

```
if sys.version_info > (2, 4):
    c_py_ssize_t = c_size_t
else:
    c_py_ssize_t = c_int
```

I think that there's no reason to keep code compat for python versions `<=2.3`. Other modules in CPython do refactor this by removing old and unused code, especially in tests.

I propose to do the same here.
