tools headers cpufeatures: Sync with the kernel sources

To pick the changes from:

690a757d610e50c2 ("kvm: x86: Add CPUID support for Intel AMX")

This only causes these perf files to be rebuilt:

CC /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
CC /tmp/build/perf/bench/mem-memset-x86-64-asm.o

And addresses this perf build warning:

Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h'
