John Tur b4f7af066e Work around codegen bug with GetKeyboardState (#41970)
Works around an issue, which can be reproduced in the following program:
```rs
use windows::Win32::UI::Input::KeyboardAndMouse::{GetKeyboardState, VK_CONTROL};

fn main() {
    let mut keyboard_state = [0u8; 256];
    unsafe {
        GetKeyboardState(&mut keyboard_state).unwrap();
    }

    let ctrl_down = (keyboard_state[VK_CONTROL.0 as usize] & 0x80) != 0;
    println!("Is Ctrl down: {ctrl_down}");
}
```

In debug mode, this program prints the correct answer. In release mode,
it always prints false. The optimizer appears to think that
`keyboard_state` isn't mutated and remains zeroed, and folds the
`modifier_down` comparisons to `false`.

Release Notes:

- N/A
