Add return type to the DeserializeGraphs function


During Deserialization of the graphs there is no return data to inform us which graphs, or how many have been added to the A* component.

Returning a list of NavGraphs from the DeserializeGraphs and DeserializeGraphsAdditive would be much appreciated.



The resulting graphs are in the AstarData.graphs array, especially for the DeserializeGraphs method this should be equivalent, right?

In our setup we have multiple scenes, that load their own graphs.
However when we want to unload the scenes there is no way to know which graphs were loaded additive.
