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

To pick the changes in:

  f97f5a56 ("x86/kvm/hyper-v: Add support for synthetic debugger interface")
  850448f3 ("KVM: nVMX: Fix VMX preemption timer migration")
  2c4c4132 ("KVM: x86: Print symbolic names of VMX VM-Exit flags in traces")
  cc440cda ("KVM: nSVM: implement KVM_GET_NESTED_STATE and KVM_SET_NESTED_STATE")
  f7d31e65 ("x86/kvm/hyper-v: Explicitly align hcall param for kvm_hyperv_exit")
  72de5fa4 ("KVM: x86: announce KVM_FEATURE_ASYNC_PF_INT")
  acd05785 ("kvm: add capability for halt polling")
  3ecad8c2 ("docs: fix broken references for ReST files that moved around")

That do not result in any change in tooling, as the additions are not
being used in any table generator.

This silences these perf build warning:
