Add GridMap function to change navigation map for baked navigation regions 

Adds function to change the navigation map for baked navigation regions.
Before all cells with a baked navigation mesh were locked to the default navigation map of the world resource.

<description>
Returns the [RID] of the navigation map this GridMap node uses for its cell baked navigation meshes.
This function returns always the map set on the GridMap node and not the map on the NavigationServer. If the map is changed directly with the NavigationServer API the GridMap node will not be aware of the map change.
