tools headers cpufeatures: Sync with the kernel sources

To pick the changes from:

  fa31a4d6 ("x86/cpufeatures: Put the AMX macros in the word 18 block")
  7b8f40b3 ("x86/cpu: Add definitions for the Intel Hardware Feedback Interface")

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'
  diff -u tools/arch/x86/include/asm/cpufeatures.h arch/x86/include/asm/cpufeatures.h
