bug#71711: 30.0.50; w32-get-ime-open-status always return t

[Eason Huang <aqua0210@foxmail.com>]

Hello Emacs,

With the latest version of Windows 10 and Windows 11, the
`w32-get-ime-open-status` and `w32-set-ime-open-status` doesn't works
anymore.

The `w32-get-ime-open-status` will alway return t.

Steps to reproduce:

1. Start Emacs with ` emacs -Q`
2. open any buffer(ex. *scratch*)
3. make sure ativate an input method, here I use the Microsoft Pinyin in
system

4. eval `w32-get-ime-open-status` in *scratch* , return t
3. eval `(w32-set-ime-open-status nil)` and then eval
`w32-get-ime-open-status`, it also return t. nil is expected
