tools arch x86: Sync asm/cpufeatures.h with the with the kernel

To pick up the changes in:

  6dbbf5ec9e1e ("x86/cpufeatures: Enumerate user wait instructions")
  b302e4b176d0 ("x86/cpufeatures: Enumerate the new AVX512 BFLOAT16 instructions")
  acec0ce081de ("x86/cpufeatures: Combine word 11 and 12 into a new scattered features word")
  cbb99c0f5887 ("x86/cpufeatures: Add FDP_EXCPTN_ONLY and ZERO_FCS_FDS")

That don't affect anything in tools/.

This silences 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'
