Express `ActionDispatch::Routing::UrlFor#route_for` as public api

This method was added by #28462 but marked as private api.
Since `route_for` looks good in pair with `ActionDispatch::Routing::Mapper::CustomUrls#direct`
let's make it as public api.
We use it in https://github.com/rails/rails/blob/e83575ff533690db86c92447a539d76b648e9fed/activestorage/config/routes.rb

Closes #31417
