Fix NavigationObstacle 2D/3D (re)parent issues 

Fixes (re)parent issues with NavigationObstacle 2D and 3D (same as NavigationAgents).
Also adds the option from NavigationAgents to override the default navigation map.

<description>
Returns the [RID] of the navigation map for this NavigationObstacle node. This function returns always the map set on the NavigationObstacle node and not the map of the abstract agent on the NavigationServer. If the agent map is changed directly with the NavigationServer API the NavigationObstacle node will not be aware of the map change. Use [method set_navigation_map] to change the navigation map for the NavigationObstacle and also update the agent on the NavigationServer.
