Add FirstEnabledTraitOrDefault helper method.

Browse Source 
This avoids the allocations caused by LINQ when using traits.FirstOrDefault(Exts.IsTraitEnabled). This is important in FrozenActorLayer.RefreshState which is called very often. We apply the new helper method to all areas using the old pattern. An overload that takes an array allows arrays to be enumerated without causing allocations.
