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

To pick the changes in:

  bfbab44568779e16 ("KVM: arm64: Implement PSCI SYSTEM_SUSPEND")
  7b33a09d036ffd9a ("KVM: arm64: Add support for userspace to suspend a vCPU")
  ffbb61d09fc56c85 ("KVM: x86: Accept KVM_[GS]ET_TSC_KHZ as a VM ioctl.")
  661a20fab7d156cf ("KVM: x86/xen: Advertise and document KVM_XEN_HVM_CONFIG_EVTCHN_SEND")
  fde0451be8fb3208 ("KVM: x86/xen: Support per-vCPU event channel upcall via local APIC")
  28d1629f751c4a5f ("KVM: x86/xen: Kernel acceleration for XENVER_version")
  536395260582be74 ("KVM: x86/xen: handle PV timers oneshot mode")
  942c2490c23f2800 ("KVM: x86/xen: Add KVM_XEN_VCPU_ATTR_TYPE_VCPU_ID")
  2fd6df2f2b47d430 ("KVM: x86/xen: intercept EVTCHNOP_send from guests")
  35025735a79eaa89 ("KVM: x86/xen: Support direct injection of event channel events")

That automatically adds support for this new ioctl:

  $ tools/perf/trace/beauty/kvm_ioctl.sh > after

This silences these perf build warning:
