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

To pick up the changes in:

  ed5194c2732c ("x86/speculation/mds: Add basic bug infrastructure for MDS")
  e261f209c366 ("x86/speculation/mds: Add BUG_MSBDS_ONLY")

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'
