[TIMEDATE] Implement the dynamic NTP status notification (#2352)

Time/Date control panel applet displays the status of the NTP server synchronization with the system informing the user the actual condition of the said sync, if it has failed or suceeded. The commit also implements IDS_INETTIMEWELCOME which serves as a placeholder as Time/Date loads the last successful attempt of NTP synchronization which I don't know how the CPL remembers it. With that said, IDS_INETTIMEWELCOME will stay for a while until someone figures out how timedate.cpl works internally.
