Arnaldo Carvalho de Melo 15d6daad8f tools headers x86 cpufeatures: Sync with the kernel sources to pick TDX, Zen, APIC MSR fence changes ...

To pick the changes from:

  1e536e1068 ("x86/cpu: Detect TDX partial write machine check erratum")
  765a0542fd ("x86/virt/tdx: Detect TDX during kernel boot")
  30fa92832f ("x86/CPU/AMD: Add ZenX generations flags")
  04c3024560 ("x86/barrier: Do not serialize MSR accesses on AMD")

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
