Apply different tagging validation per country in iD

[skyper]

@Minh_Nguyen

The validator warning occurs because the combination of highway=cycleway foot=designated looks similar to the tags for the Cycle & Foot Path preset, which has those two tags plus bicycle=designated.

Nice, in Germany highway=cycleway foot=designated is simply wrong. Adding only bicycle=designated is not fixing the problem but either foot=designated is wrong or it should be highway=path bicycle=designated foot=designated.
