hv: add ACPI support for pre-launched VMs

Browse Source 
Statically define the per vm RSDP/XSDT/MADT ACPI template tables in vacpi.c,
RSDP/XSDT tables are copied to guest physical memory after checksum is
calculated. For MADT table, first fix up process id/lapic id in its lapic
subtable, then the MADT table's checksum is calculated before it is copies to
guest physical memory.

Add 8-bit checksum function in util.h
