apic polarity in KVM does not work: too many things assume active high.
Let's not pretend it works, let's just ignore polarity flag. If we ever
want to emulate it exactly, this will need a feature flag anyway.
Also report this to userspace: this makes it
possible to report the interrupt active-lo

Why?
We already have different ACPI tables for TCG vs KVM.
Specifically apic interrupt override flag in MADT is set
for KVM but not TCG.
It used to be this way, but
bool kvm_allows_irq0_override(void)
{
return !kvm_irqchip_in_kerne
