Intel IceLake cpu has added new cpu features: AVX512VBMI2/GFNI/
VAES/AVX512VNNI/AVX512BITALG/VPCLMULQDQ. Those new cpu features
need expose to guest.
The bit definition:
CPUID.(EAX=7,ECX=0):ECX[bit 06] AVX512VBMI2
CPUID.(EAX=7,ECX=0):ECX[bit 08] GFNI
CPUID.(EAX=7,ECX=0):ECX[bit 09] VAES
CPUID.(EAX=7,ECX=0):ECX[bit 10] VPCLMULQDQ
CPUID.(EAX=7,ECX=0):ECX[bit 11] AVX512VNNI
CPUID.(EAX=7,ECX=0):ECX[bit 12] AVX512_BITALG
