Replace deprecated usage of url() and urlInfo()

@Satyanarayan Reddy Thanks!!!

We are missing url(), let's do those in the same patch

Let's add credit to @Munavijayalakshmi who worked on #2875917: Replace deprecated entity->urlInfo() method with entity->toUrl()., and let's use this issue instead of that one.

This looks great, thanks!

   For backwards compatibility, $url_generator should be NULL by default and we should trigger an error.

   Like:

       if (!$entity_type_manager) {
         @trigger_error('The entity_type.manager service must be passed to LingotekConfigSubscriber::__construct, it is required before Lingotek 9.x-1.0. See https://www.drupal.org/node/2549139.', E_USER_DEPRECATED);

   Same here.

That looks really good, thanks! Re-testing as those test errors are unrelated.

Committed 46920a6 and pushed to 8.x-2.x. Thanks all involved!
