[openstreetmap/openstreetmap-website] Add profile-specific request parameters for Valhalla (Issue #7236)

[Nils]

nilsnolde created an issue (openstreetmap/openstreetmap-website#7236)

### Problem

A handful of time per year we get wonky issues from Valhalla routing on https://www.openstreetmap.org/, e.g. https://github.com/valhalla/valhalla/discussions/6215. 

Most often they're sub-optimal parameterization of the request. Quick background: Valhallla operates _all_ costing models (car, bike etc) on a single graph, while OSRM & GH of course not. That also means it's impossible to have a single request parameter set be optimal for all costing models/profiles.

Hence I'd ask if you're fine if we add logic which switches costing options for the request by profile for Valhalla? I didn't go look at the code yet, only at https://github.com/openstreetmap/openstreetmap-website/pull/3848.
