Properly handle Windows updates during shutdown

Browse Source 
Windows updates are applied on shutdown/reboot no matter of flags used
in ExitWindowsEx (or InitiateShutdown).

Windows start menu shutdown code handles updates in special way.
If there are updates prepared and shutdown/reboot is selected it will
use `UpdateSessionOrchestrator` object to dismiss updates and carry out
the command.

We will now do similar thing.

Fixes #1250
