tools headers cpufeatures: Sync with the kernel sources
To pick the changes in:
7c1ef59145f1c8bf ("x86/cpufeatures: Re-enable ENQCMD")
That causes only these 'perf bench' objects to rebuild:
CC /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
CC /tmp/build/perf/bench/mem-memset-x86-64-asm.o
And addresses these perf build warnings:
Warning: Kernel ABI header at 'tools/arch/x86/include/asm/disabled-features.h' differs from latest version at 'arch/x86/include/asm/disabled-features.h'
