16e365d7a4 Clarify use of forcing routing steps
The change clarifies the conditions for forcing routing steps and
simplifies the codebase to support it.

- Makes explicity  the search runtime condition for forcing a routing
step. Namely, the node is a source of the forward and reverse searches,
and it's one of the pre-identified nodes that requires a step to
be forced.
- Consolidate the two lists of force nodes into one. Not only is there
no algorithmic value in separating the nodes by geometric direction,
the  improvements to via-routes with u-turns mean atleast one of these
lists will be empty for any search.
- Rename 'force loop' to 'force step'. This moves the code away
from the original CH-specific language for checking for self-loops
in the case where this condition is met. MLD does not have loops.

Additional cucumber tests are added to cover the logic related to
negative search weights and forcing routing steps on via-route
paths.

Make edge metrics strongly typed (#6421)
This change takes the existing typedefs for weight, duration and
distance, and makes them proper types, using the existing Alias
functionality.

Primarily this is to prevent bugs where the metrics are switched,
but it also adds additional documentation. For example, it now
makes it clear (despite the naming of variables) that most of the
trip algorithm is running on the duration metric.

I've not made any changes to the casts performed between metrics
and numeric types, they now just more explicit.

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