[USER32] Small fixes for messages carrying pointers

Browse source 
SendNotifyMessageW: It doesn't support messages with pointers so there is no need to call MsgiUMToKMMessage
SendMessageTimeoutW, SendMessageTimeoutA: These two do support marshaling pointers so they need to use MsgiUMToKMMessage.
This is actually a bug that happens only in the rare case where we send a WM_COPYDATA with a timeout.
