Displays detailed information about the CPU(s) gathered from the
CPUID instruction, and also determines the exact model of CPU(s).
Where /proc/cpuinfo shows features important to a system, cpuid shows
what every feature in each CPU's architecture does.
It is updated and released frequently to stay current with Intel and
AMD information and supports other vendors' chips.

- For AMD Zen CPUs, overhauled uarch & synth decoding to determine the
CPU model from only the extended model & high bit of the model field.
Also, determine the stepping (revision) mechanically from the
low-order 3 bits of the model and the stepping number.
This should correctly identify retail Zen 5 Ryzens.
This also corrects some stepping bugs from the Zen 1 era.
