[Maxim Polyakov (Code Review)]

Hello Patrick Rudolph, Felix Held, Angel Pons, David Hendricks, Stefan Reinauer, Lance Zhao, build bot (Jenkins), Andrey Petrov,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).

util/inteltool: Add server 5065x CPU model support

Adds the MSR table for server family 6 model 85 (5065x) processors (Sky
Lake, Cascade Lake, Cooper Lake).

The cores number for these processors exceeds the limit of 8 cores
(it is hardcoded in cpu.c). For this reason, the patch also adds code
that determines the number of processor cores at run time.

These changes are in accordance with the documentation:
[*] pages: 2-265 ... 2-286, 2-297 ... 2-308.
    Intel(R) 64 and IA-32 Architectures, Software Developer’s Manual,
    Volume 4: Model-Specific Registers. May 2019.
    Order Number: 335592-070US

TODO: Perhaps need to dump "SHARED MSRs" for each processor in
      a multiprocessor server.
