Sainath Grandhi ff56b6f62d hv: Add support for leaf 0xb emulation ...

ACRN does not support platforms that do not have x2APIC mode of LAPIC
in hardware. With this patch, x2APIC is exposed to guests by default.

Extended Topology Leaf 0xb in cpuid returns x2APIC ID and topology
information to OS. This patch adds support to return guest topology
and guest x2APIC ID. Number of SMT siblings is returned as 0.
