    [NTUSER] Remember old KL for Chinese IMEs (#5266)
    
    The Chinese user uses Ctrl+Space key combination to switch between the IME keyboard
and the non-IME keyboard. To enable Ctrl+Space, the system has to remember the previous
keyboard layout. In IntImmActivateLayout function, remember the previous keyboard layout
(hklPrev) to switch back for Chinese IMEs. CORE-18950
