hv: implement NEED_SHUTDOWN_VM request to idle thread

Browse Source 
For pre-launched VMs and SOS, VM shutdown should not be executed in the
current VM context.

- implement NEED_SHUTDOWN_VM request so that the BSP of the target VM can shut
  down the guest in idle thread.
- implement shutdown_vm_from_idle() to shut down target VM.
