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:
