Junjie Mao 598be99dc2 board_inspector/cpuparser: add CPUID parsers
This patch adds a parser of CPU identification information reported by the
CPUID instruction.

The framework is based on the CPUID parsing facilities in
BITS (https://biosbits.org/), but with the following changes.

1. The CPUID data is fetched by executing the `cpuid` utility, rather than
   executing the `cpuid` instruction. This avoids introducing any
   additional library or Python/C extension and gets a CPUID leaf on all
   physical cores in one shot.

2. Parsers of CPUID leaves 0x10, 0x1A and 0x1F are added. New fields in
   existing leaves are also added.

3. A wrapper function, named `parse_cpuid`, is added as the single API that
   allows other modules to get an arbitrary CPUID leaf or subleaf.

ACRN Tools
##########

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

This folder holds the source to a number of tools that facilitate the
management, debugging, profiling, and logging of multi-OS systems based on
ACRN.

You can find out more about Project ACRN and its set of tools on the
`Project ACRN documentation`_ website.
