I think it's cleaner to keep separate CreateForConsole and
CreateForVirtualTerminal constructors here, for clarity.

If you're doing that then you can also move the DesktopSessionWin implementation
back here, move the ctor, dtor and interface overrides to be private or
protected, and have a pair of static CreateForX members.
