Fix for WG-72024 will make many tiny heap allocations every frame - performance risk.

Question

TSet::ToArray makes heap allocations.  Given how frequently RefreshObstructionAndOcclusion is called, if (in_Listeners.Array().FindByPredicate(ListenerIDsMatch) == nullptr) is likely to put undue pressure on memory allocation.

I made a slightly different change at the top of that loop.  Would you be willing to merge it?
 

bool bFoundValid = false;
for (TWeakObjectPtr<UAkComponent> InListener : in_Listeners)
{
    if (InListener.IsValid() && InListener->GetAkGameObjectID() == Listener)
    {
       bFoundValid = true;
       break;
    }
}

if (!bFoundValid)
{
    It.RemoveCurrent();
    continue;
}
