Revert "DEV: add routes_lazy_route to boost boot-up time (#14545)" (#14581)

This reverts commit f5cf647e57.

The gem breaks usage of Rails URL helpers when used outside views and
controllers, for example in
88ecb83382/app/models/upload.rb (L239-L242)
the `upload_short_path` method call fails with an undefined method
exception when this gem is enabled.
