Implements this : godotengine/godot-proposals#691 (comment)
Finally we can get rid of those nodes. This avoid the need for NavigationRegion to have them as a direct parent, or, for any NavigationAgent or NavigationObstacle, to have them in their ancestors.
To replace them, the navigation map RID they used to hold has been moved to the world2D/3D resource.
This PR is a draft, as for now there is no way to have multiple maps per world, as we used to. I'll add a similar feature in a second commit by adding a system of layers/masks to the different regions/agents. It will work as it does for physics layers.
Edit: It seems that things works correctly in the 2D demo with little changes to the project. The 3D demo does not work in 4.0 (no meshes appears), so I cannot test.
