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

To pick the changes in:

  86bdf3eb ("KVM: Support dirty ring in conjunction with bitmap")

That just rebuilds perf, as these patches don't add any new KVM ioctl to
be harvested for the the 'perf trace' ioctl syscall argument
beautifiers.

This is also by now used by tools/testing/selftests/kvm/, a simple test
build didn't succeed, but for another reason:

  lib/kvm_util.c: In function ‘vm_enable_dirty_ring’:
  lib/kvm_util.c:125:30: error: ‘KVM_CAP_DIRTY_LOG_RING_ACQ_REL’ undeclared (first use in this function); did you mean ‘KVM_CAP_DIRTY_LOG_RING’?
    125 |         if (vm_check_cap(vm, KVM_CAP_DIRTY_LOG_RING_ACQ_REL))
        |                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        |                              KVM_CAP_DIRTY_LOG_RING

I'll send a separate patch for that.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
  diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h
