tools arch x86: Sync the msr-index.h copy with the kernel sources

To pick up the changes from these csets:

  159013a7 ("x86/its: Enumerate Indirect Target Selection (ITS) bug")
  f4138de5 ("x86/msr: Standardize on u64 in <asm/msr-index.h>")
  ec980e4f ("perf/x86/intel: Support auto counter reload")

That cause no changes to tooling as it doesn't include a new MSR to be
captured by the tools/perf/trace/beauty/tracepoints/x86_msr.sh script.

Just silences this perf build warning:

  Warning: Kernel ABI header differences:
    diff -u tools/arch/x86/include/asm/msr-index.h arch/x86/include/asm/msr-index.h
