Copy arch/x86/include/asm/acpufeature.h and arch/x86/kvm/reverse_cpuid.h
from the kernel so that KVM selftests can use them in the next commits.
Also update the tools copy of arch/x86/include/asm/acpufeatures.h.
cpufeature.h is copied into tools/arch/x86/include like most other
headers. reverse_cpuid.h is a special case as it's copied into the KVM
selftests include location: tools/testing/selftests/kvm/include/x86_64/.
These should be kept in sync, ideally with the help of some script like
check-headers.sh used by tools/perf/.
