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

To pick up the changes in:

  3915035282573c5e ("KVM: x86: SVM: move avic definitions from AMD's spec to svm.h")

Addressing these tools/perf build warnings:

    diff -u tools/arch/x86/include/asm/msr-index.h arch/x86/include/asm/msr-index.h
    Warning: Kernel ABI header at 'tools/arch/x86/include/asm/msr-index.h' differs from latest version at 'arch/x86/include/asm/msr-index.h'

That makes the beautification scripts to pick some new entries:

  $ 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

And this gets rebuilt:

  CC      /tmp/build/perf/trace/beauty/tracepoints/x86_msr.o
  LD      /tmp/build/perf/trace/beauty/tracepoints/perf-in.o

Now one can trace systemwide asking to see backtraces to where those
MSRs are being read/written with:

  # perf trace -e msr:*_msr/max-stack=32/ --filter="msr>=AMD64_SVM_AVIC_DOORBELL && msr<=AMD64_SEV_ES_GHCB"
  ^C#

If we use -v (verbose mode) we can see what it does behind the scenes:

  # perf trace -v -e msr:*_msr/max-stack=32/ --filter="msr>=AMD64_SVM_AVIC_DOORBELL && msr<=AMD64_SEV_ES_GHCB"
  Using CPUID AuthenticAMD-25-21-0
  0xc001011b
  0xc0010130
  New filter for msr:read_msr: (msr>=0xc001011b && msr<=0xc0010130) && (common_pid != 1019953 && common_pid != 3629)
  0xc001011b
  0xc0010130
  New filter for msr:write_msr: (msr>=0xc001011b && msr<=0xc0010130) && (common_pid != 1019953 && common_pid != 3629)
  mmap size 528384B
  ^C#

  Example with a frequent msr:

    # perf trace -v -e msr:*_msr/max-stack=32/ --filter="msr==IA32_SPEC_CTRL" --max-events 2
    Using CPUID AuthenticAMD-25-21-0
    0x48
    New filter for msr:read_msr: (msr==0x48) && (common_pid != 2612129 && common_pid != 3841)
    0x48
    New filter for msr:write_msr: (msr==0x48) && (common_pid != 2612129 && common_pid != 3841)
    mmap size 528384B
