hv: add support for shutdown for pre-launched VMs

Browse Source 
Currently, ACRN only support shutdown when triple fault happens, because ACRN
doesn't present/emulate a virtual HW, i.e. port IO, to support shutdown. This
patch emulate a virtual shutdown component, and the vACPI method for guest OS
to use.

Pre-launched VM uses ACPI reduced HW mode, intercept the virtual sleep control/status
registers for pre-launched VMs shutdown
