[USER32] Implement User32CreateImeUI (#4316)

Browse source 
Implementing Japanese input...
- Add User32CreateImeUIWindow, User32GetImeShowStatus, User32SendImeUIMessage, User32UpdateImcOfImeUI, User32SetImeWindowOfImc and User32NotifyOpenStatus helper functions.
- Add WM_IME_SELECT, WM_IME_COMPOSITION, WM_IME_STARTCOMPOSITION and WM_IME_ENDCOMPOSITION message handling of the IME window.
- Rename ImeWnd_OnDestroy as User32DestroyImeUIWindow.
- Rename CheckIMCForWindow as User32CanSetImeWindowToImc.
- Improve ImeWnd_OnCreate function.
