Katayama Hirofumi MZ 242e0b4303
[NTUSER][USER32] Implement IME status (#4472) 
- Add IntCheckImeShowStatus, IntSendMessageToUI, IntSendOpenStatusNotify, IntNotifyImeShowStatus, and xxxBroadcastImeShowStatusChange helper functions.
- Renaming: s/X_ROUTINE_IMESHOWSTATUSCHANGE/TWOPARAM_ROUTINE_IMESHOWSTATUSCHANGE/
- Implement NtUserCallNoParam.NOPARAM_ROUTINE_GETIMESHOWSTATUS.
- Implement NtUserCallHwndParamLock.TWOPARAM_ROUTINE_IMESHOWSTATUSCHANGE.
- Fix hung in User32GetTopLevelWindow and rename it as IntGetTopLevelWindow.
