812edc95a3 conf: cpu: Add <signature family=X model=X stepping=X/> 
Internally we already collect x86 host family + model + stepping
numeric values. This exposed them in capabilities CPU output.
Example:

$ sudo virsh capabilities | grep -A1 -B1 signature
      <microcode version='240'/>
      <signature family='6' model='94' stepping='3'/>
      <counter name='tsc' frequency='3408010000' scaling='no'/>

Users need to know these values to calculate an expected.
SEV-ES/SEV-SNP launch measurement.

a32cc82793 cpu_map: Drop 'monitor' from modern x86 CPU models 
The feature is never enabled by default on KVM and QEMU dropped it from
the models long ago.

a0b628432a cpu: Add new EPYC CPU model 
Add a new CPU model called 'EPYC' to model processors from AMD EPYC
family (which includes EPYC 76xx,75xx,74xx, 73xx and 72xx).

The following features bits have been added/removed compare to Opteron_G5

Added: monitor, movbe, rdrand, mmxext, ffxsr, rdtscp, cr8legacy, osvw,
       fsgsbase, bmi1, avx2, smep, bmi2, rdseed, adx, smap, clfshopt, sha
       xsaveopt, xsavec, xgetbv1, arat

Removed: xop, fma4, tbm

The patch is depend on EPYC CPU model supported introduced in qemu [1]
