From: Sean Christopherson <sean.j.christopher...@intel.com>
Return true for kvm_vcpu_has_events() if the vCPU has a pending APICv
interrupt to support TDX's usage of APICv. Unlike VMX, TDX doesn't have
access to vmcs.GUEST_INTR_STATUS and so can't emulate posted interrupts,
i.e. needs to generate a posted interrupt and more importantly can't
manually move requested interrupts into the vIRR (which it also doesn't
have access to).
