Cycleway overlay: Differentiate bicycle access on pedestrian roads

[westnordost]

fixes #6016

Changes:

• pedestrian roads are now colored like footways: black by default, aquamarine when bicycles are allowed, cyan when also designated to bicycles
• added other-answer options (only displayed for pedestrian streets) to switch between these.
• Cannot select bicycle road for pedestrian streets
• current bicycles-on-pedestrian-road situation is displayed in form UI
• also for bicycle roads: the displayed sign is not modal anymore, i.e. can specify left-and-right-situation, too

My findings for d3a6c2b

Pavement mode:

• pedestrian street is not visible. (Like visibility of bicycle=yes at pedestrian zones #6016 but for pavement mode)

Cycleway mode:

• three dot menu entries:
  "No explicit sign about cycling here" + "A sign allows cycling here" + "Designated for cycling here"
  ... are accessible when selecting residential road, bicycle boulevard, secondary road, motorway. Not needed because of the normal cycleway UI.
• when adding protected bicycle lanes to both sides of a pedestrian road, colored lines appear e.g. for Weserpromenade, how it should be. But, it is only shown on one side for my example way. I think it's because of an overlaying area tagged as pedestrian zone.

Cool, thanks for testing it!

I don't understand your comment about "pavement mode". Could you add a screenshot or something?

Oh! Weird, I thought I tested that. Will fix before merge.

Yes, overlaying things will overlay, ¯_(ツ)_/¯. However, pedestrian areas shouldn't actually be highlighted at all in this overlay and thus also not appear in front of these things. I will have a look.

Pedestrian street could be made visible like foot paths:

Ah I see, well, makes sense, but I'll implement that separately.

One more litte remark. Maybe it is supposed to be, but:
The "sign allows cycling" or "designated for cycling" option disappears from three dot menu if it is the current status of the way. "No explicit sign" option is always shown.

That's it. Thank you for your work :)

[westnordost]

Oh, yes, that's another bug

Thanks for the review, @FloEdelmann !
