tools headers UAPI: Sync kvm.h headers with the kernel sources

None entails changes in tooling, the closest to that were some new arch specific ioctls, that are still not handled by the tools/perf/trace/beauty/ library, that needs to create per-arch tables to convert ioctl cmd->string (and back).

From a quick look the arch specific kvm-stat.c files at:

  $ ls -1 tools/perf/arch/*/util/kvm-stat.c
  tools/perf/arch/powerpc/util/kvm-stat.c
  tools/perf/arch/s390/util/kvm-stat.c
  tools/perf/arch/x86/util/kvm-stat.c
  $

Are not affected.

This silences these perf building warnings:
