Add traits for new AVX512 CPU feature

Browse Source 
To support new AVX512 cpu feature, this patch adds the mapping
between cpu features reported by libvirt [1] and corresponding
os-traits [2]. The traits include 'AVX512VBMI', 'AVX512IFMA',
'AVX512VBMI2', 'AVX512BITALG', 'AVX512VAES', 'AVX512GFNI',
'AVX512VPCLMULQDQ' and 'AVX512VPOPCNTDQ'.
