arch: vmm: Move ACPI tables creation to vmm crate

Remove ACPI table creation from arch crate to the vmm crate simplifying
arch::configure_system()

GuestAddress(0) is used to mean no RSDP table rather than adding
complexity with a conditional argument or an Option type as it will
evaluate to a zero value which would be the default anyway.
