Use surface in addition to tracktype for highway=track

[HolgerJeromin]

I never liked the tracktype numbers, so i added only a surface tag. But sadly this style does only support tracktype on tracks.
This raises the question which tag has priority. I would fallback to surface if no tracktype is there.
Related to #110

no, it's not about "priority", because the issue is about showing both, tracktype and surface.

A small solution would be fallback to surface if no tracktype is there. But this would be revisited by implementing #110.
While i am not sure if you can squeeze tracktype and surface in one visualisation. But this should be discussed not here.

I am pretty sure that it is not feasible, and I would expect these values to generally be consistent (there are cases like extremely overgrown asphalt track, but it is fairly rare)

Closing this since rendering both tracktype and surface does not seem to be feasible, removing tracktype rendering is suggested in #4322 instead.

I guess it could be confusing ;) but it wouldn't be technically impossible to show both, tracktype and surface, e.g. tracktype could be shown as line width and surface through dashes. Or opacity for tracktype. Or encode something in the casing...
