dongshen 5e3c6ae941 hv: vcpuid: passthrough host CPUID leaf.0BH to guest VMs
Using physical APIC IDs as vLAPIC IDs for pre-Launched and post-launched VMs
is not sufficient to replicate the host CPU and cache topologies in guest VMs,
we also need to passthrough host CPUID leaf.0BH to guest VMs, otherwise,
guest VMs may see weird CPU topology.

Note that in current code, ACRN has already passthroughed host cache CPUID
leaf 04H to guest VMs
