Extend CPUID emulation to support XFD, AMX_TILE, AMX_INT8 and AMX_BF16. Adding those bits into kvm_cpu_caps finally activates all previous logics in this series.
Hide XFD on 32bit host kernels. Otherwise it leads to a weird situation where KVM tells userspace to migrate MSR_IA32_XFD and then rejects attempts to read/write the MSR.

No need for my SoB, I provided a very tiny snippet of code review.
It's not tiny if compared to the rest of the patch, but we certainly can remove it. anyway thanks for all your suggestions which are all good. 😊
