hv: Use virtual APIC IDs for Pre-launched VMs

Browse Source 
For Pre-launched VMs, ACRN uses mptable for reporting APIC IDs to guest OS.
In current code, ACRN uses physical LAPIC IDs for vLAPIC IDs.
This patch is to let ACRN use vCPU id for vLAPIC IDs  and also report the same
when building mptable. ACRN should still use physical LAPIC IDs for SOS
because host ACPI tables are passthru to SOS.
