exo: Add toast shell for ARC++ toasts
This CL introduces a new shell type for ARC++ toasts in remote-shell.
Since the purpose of toasts is a notification for users and the toast
appears and disappears quickly without any user interaction, so toasts
are supposed to be shown over Chrome OS's virtual keyboard.
