Expose the collider RID in Raycast nodes

Browse source 
Create and expose the method `get_collider_rid` in `RayCast2D` and `Raycast3D`.
This method returns the `RID` of the first object that the ray intersects, or an empty `RID` if no object is intersecting the fay (i.e. `is_colliding` returns `false`).
