Add Stop-VM to Terminal shelf context menu

We want users to be able to stop the entire Termina VM via the shelf
icon context menu for the (Crostini) Terminal. This is already possible
via the app list.

To achieve this I needed to add a new CommandID, as menu_close was
already used. This does not seem ideal, however there is a chance
that this command will be useful for other VMs later.
