tools headers cpufeatures: Sync with the kernel sources

To pick the changes from:

  9678f037865fd3b1 ("x86/cpufeatures: Add PerfMonV2 feature bit")
  391fb42400dcb232 ("KVM: SEV-ES: Use V_TSC_AUX if available instead of RDTSC/MSR_TSC_AUX intercepts")
  8099d3b5ad204f2b ("x86/cpufeatures: Add virtual TSC_AUX feature bit")
  a787e72d6ac58c36 ("x86/fpu/xsave: Support XSAVEC in the kernel")
  89b4b89d75694faf ("x86/tdx: Detect running as a TDX guest in early boot")
  f1d2777f449a87ea ("x86/cpufeatures: Add AMD Fam19h Branch Sampling feature")

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
