[KERNEL32][CONSRV]
Implement (undocumented) SetLastConsoleEventActive API.
Patch by Alexander Andrejevic, with a minor modification by me concerning the addition of
a NotifiedLastCloseProcess member to the CONSOLE structure and a check that makes sure
that only the app that asked for the notification, receives it (and so that we don't
call the console control dispatcher for nothing).
This API is used by ntvdm to be sure that it gets killed when all other console apps
attached to the ntvdm's console are away.
