[HVM][Firmware] Make the creation of MP tables more dynamic

Currently the ROMBIOS includes static MP tables for only four
configurations: 1-way, 2-way, 4-way, and 8-way.

This patch makes the creation of MP tables more dynamic by creating them
from within HVMLOADER based upon the VCPU number provided by the HVM
information table.

Note: Some of the information included used to create the MP tables is
still hard coded and based upon values used in the original ROMBIOS MP
tables.  Data such as the CPU family/model/stepping information should
probably be made to match the information provided to the guest when
executing a CPUID.
