Ask for smoothness on segregated Cycle & Foot paths

[rhhsm]

For segregated Cycle & Foot paths (highway=cycleway/footway/path + bicycle=designated + foot=designated + segregated=yes), SC currently asks for surface of both the cycle path and the foot path. However, these kind of paths are not yet included in the smoothness quest. I see no reason why they shouldn't be included, i.e. for highway=cycleway/footway/path that have cycleway:surface=* and/or footway:surface=*, smoothness should be quested so that cycleway:smoothness and footway:smoothness are set. The same UI that is used for the surface quest for these paths can be used.

In addition, the Dutch tagging tradition of seeing these kind of paths as a cycle path with a sidewalk for pedestrians should also be taken into account, i.e. ways like this one https://www.openstreetmap.org/way/6547886 should also be quested for the smoothness of both cycle path and sidewalk.

There may be other properties like width (that I'm not tagging) that are not quested for these kinds of highways (that's why I thought my idea was related to #5445)

Minus the note about sidewalks, this could be an enhancement of the smoothness quest.

Why? Maybe because you're afraid the next thing I'm going to suggest is to ask for smoothness for all sidewalks? I've been thinking about that, but it would be an awful lot of work to survey... ;)

Asking for sidewalk:surface is already asking smoothness for all sidewalks, be it on a road or on a cycleway.
Though this case is unclear to me, is it really a segragated cycleway with sidewalk? I.e. two lanes for foot where the foot smoothness should be asked twice?
