gh-104533: Use @ctypes.util.struct decorator

[vstinner]

Use also @ctypes.util.wrap_dll_function() decorator.

• Issue: Annotation-based syntax for ctypes structs #104533

Oh, I had to revert changes because I found multiple bugs in @ctypes.util.struct.

Oh, I had to revert changes because I found multiple bugs in @ctypes.util.struct:

• Bug 1: PR gh-104533: Fix @ctypes.util.struct with endian #154038, struct with endian
• Bug 2: PR gh-104533: Fix @ctypes.util.struct with string annotations #154040, from __future__ import annotations

I converted structures of Lib/_pyrepl/windows_console.py to @ctypes.util.struct. The problem is that this file is tested by mypy with Python 3.15 which doesn't know about @ctypes.util.struct. So I reverted _pyrepl changes.

[vstinner]

There are many structures defined in:

• Lib/test/leakers/test_ctypes.py
• Lib/test/test_ctypes/
• ctypes.util
• ctypes.wintypes
• _pyrepl.windows_console

For _pyrepl, I left it unchanged because of the mypy issue described above.

ctypes sub-modules cannot use @ctypes.util.struct because they are used by ctypes.util (inter-dependencies).

test_ctypes contains just too many structures, I'm not suret that it's worth it to convert all of them.
