Support snapping to multiple ways at an input location (#5953)

Browse Source 
This PR improves routing results by adding support for snapping to
multiple ways at input locations.

This means all edges at the snapped location can act as source/target
candidates for routing search, ensuring we always find the best route,
and not the one dependent on the edge selected.
