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

To pick up the changes from:

  a25bbc2644f0 ("Merge branches 'x86-cpu-for-linus' and 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip")
  db4d30fbb71b ("x86/bugs: Add ITLB_MULTIHIT bug infrastructure")
  1b42f017415b ("x86/speculation/taa: Add mitigation for TSX Async Abort")
  9d40b85bb46a ("x86/cpufeatures: Add feature bit RDPRU on AMD")

These don't cause any changes in tooling, just silences this perf build
