    tools headers UAPI: Sync KVM's vmx.h header with the kernel sources

    To pick the changes in:

      6c441e4 ("KVM: TDX: Handle EXIT_REASON_OTHER_SMI")
      c42856a ("KVM: TDX: Add a place holder for handler of TDX hypercalls (TDG.VP.VMCALL)")

    That makes 'perf kvm-stat' aware of this new TDCALL exit reason, thus
    addressing the following perf build warning:

      Warning: Kernel ABI header differences:
