Ensure network autonomy gets set before entity activation on non-dedicated servers

-Exposes an AutoActivate flag to INetworkEntityManager and ensured it got respected for all paths
-Tweak SpawnDefaultPlayerPrefab to not immediately activate its spawned entity to allow SetAllowAutonomy to be picked up from the net bind component during component activation
