Alexandre Derumier 1359e23fb4 cpuconfig: add new x86-64-vX models

"
In 2020, AMD, Intel, Red Hat, and SUSE worked together to define
three microarchitecture levels on top of the historical x86-64
baseline:

  * x86-64:    original x86_64 baseline instruction set
  * x86-64-v2: vector instructions up to Streaming SIMD
               Extensions 4.2 (SSE4.2)  and Supplemental
               Streaming SIMD Extensions 3 (SSSE3), the
               POPCNT instruction, and CMPXCHG16B
  * x86-64-v3: vector instructions up to AVX2, MOVBE,
               and additional bit-manipulation instructions.
  * x86-64-v4: vector instructions from some of the
               AVX-512 variants.

This patch add new builtin model derivated from qemu64 model,
to be compatible between intel/amd.

x86-64-v1 : I'm skipping it, as it's basicaly qemu64|kvm64 -vme,-cx16 for compat Opteron_G1 from 2004
            so will use it as qemu64|kvm64 is higher are not working on opteron_g1 anyway
