util/intelmetool: Add bootguard information dump support
With this implementation it's possible to detect the state
of bootguard in intel based systems. Currently it's WIP and
in a testphase. Handle it with care!
Changes done:
* Add support for reading msr
* Read ME firmware version
* Print bootguard state for ME > 9.1
* Make argument -s legacy
* Add argument -b for bootguard (and ME) dumping
* Add argument -m for ME dumping
* Opt out early if CPU is non Intel
