tools headers svm: Sync svm headers with the kernel sources



To pick the changes in:

  b8c3c9f5 ("x86/apic: Initialize Secure AVIC APIC backing page")

That triggers:

  CC      /tmp/build/perf-tools/arch/x86/util/kvm-stat.o
  LD      /tmp/build/perf-tools/arch/x86/util/perf-util-in.o
  LD      /tmp/build/perf-tools/arch/x86/perf-util-in.o
  LD      /tmp/build/perf-tools/arch/perf-util-in.o
  LD      /tmp/build/perf-tools/perf-util-in.o
  AR      /tmp/build/perf-tools/libperf-util.a
  LINK    /tmp/build/perf-tools/perf

But this time causes no changes in tooling results, as the introduced
SVM_VMGEXIT_SAVIC exit reason wasn't added to SVM_EXIT_REASONS, that is
used in kvm-stat.c.

And addresses this perf build warning:

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

Please see tools/include/uapi/README for further details.
