message: vertexcodec: Specify all AVX512 extensions we need
  Some instructions are predicated on instruction sets like VBMI and VL;
  while there's no hardware that supports VBMI2 and doesn't support VBMI
  or VL, when manually specifying instruction sets in command line this
  becomes important to get right.
