KVM: x86: Rename CPUID feature bit AVX10_VNNI_INT to AVX10_V1_AUX
Rename AVX10_VNNI_INT is to AVX10_V1_AUX to match the most recent version
of the AVX10.2 spec (revision 7.0) [*]. Intel renamed the CPUID flag to
apply to a variety of "convert" instructions as well as VNNI instructions.
[*] Intel® Advanced Vector Extensions 10.2 Architecture Specification (rev 7.0)
