RH-Commit: [1/1] 1afb03048c674b54da8cd4ad5174f767a7514b51 (anisinha/centos-qemu-kvm)

RHEL-10 has switched to a new baseline microarchitecture called "x86-64-v3".
Deprecate the CPU models that do not support x86-64-v3. The following are the
CPU models that do not support v3:

Intel: Denverton, IvyBridge, Nehalem, SandyBridge, Snowridge, Westmere.
AMD: Opteron_G4 and Opteron_G5.
