tools headers x86 cpufeatures: Sync with the kernel sources to pick ZEN6 and Indirect Target Selection (ITS) bits

To pick the changes from:

  24ee8d9432b5744f ("x86/CPU/AMD: Add X86_FEATURE_ZEN6")
  2665281a07e19550 ("x86/its: Add "vmexit" option to skip mitigation on some CPUs")
  8754e67ad4ac692c ("x86/its: Add support for ITS-safe indirect thunk")
  159013a7ca18c271 ("x86/its: Enumerate Indirect Target Selection (ITS) bug")

This causes these perf files to be rebuilt and brings some X86_FEATURE
that will be used when updating the copies of
tools/arch/x86/lib/mem{cpy,set}_64.S with the kernel sources:

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

Please see tools/include/uapi/README for further details.
