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

To pick up the changes from these csets:

  1b5277c ("x86/srso: Add SRSO_NO support")
  8974eb5 ("x86/speculation: Add Gather Data Sampling mitigation")

That cause no changes to tooling:

  $ tools/perf/trace/beauty/tracepoints/x86_msr.sh > before
  $ cp arch/x86/include/asm/msr-index.h tools/arch/x86/include/asm/msr-index.h
  $ tools/perf/trace/beauty/tracepoints/x86_msr.sh > after
  $ diff -u before after
  $

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
