tools headers svm: Sync svm headers with the kernel sources

To pick the changes in:

  8c29f01 ("x86/sev: Add SEV-SNP guest feature negotiation support")

That triggers:

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

But this time causes no changes in tooling results, as the introduced
SVM_VMGEXIT_TERM_REQUEST 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 at 'tools/arch/x86/include/uapi/asm/svm.h' differs from latest version at 'arch/x86/include/uapi/asm/svm.h'
  diff -u tools/arch/x86/include/uapi/asm/svm.h arch/x86/include/uapi/asm/svm.h
