Argument Count Error in Drupal Core prior to 11.4 missing contextual links helper

Root cause: commit ae78ed7 (from #3612695) added a ContextualLinksHelper constructor parameter to ViewsReferenceFieldFormatter without adding a matching create() override. FormatterBase::create() passes the standard 7 arguments, so every render of a viewsreference field throws the ArgumentCountError above — current 2.x HEAD is broken for all sites tracking 2.x-dev.

There is a second problem behind it: \Drupal\views\ContextualLinksHelper only exists in core 11.4+, while this module declares core_version_requirement: ^10 || ^11 || ^12. Even with a correct create() override, sites on 10.x or 11.0–11.3 would still fatal, because neither the class nor its autowired service exists on those cores.

The attached patch fixes both:

- adds the create() override, injecting the helper via $container->has(ContextualLinksHelper::class) so it resolves to NULL on cores that predate the service;
- makes the constructor parameter nullable (?ContextualLinksHelper $contextualLinksHelper = NULL);
- guards both call sites (?-> in ViewsReferenceFieldFormatter, \Drupal::hasService() in ViewsReferenceLazyFieldFormatter) so contextual links are simply not added on older cores — the same behavior those sites had before ae78ed7.

Workaround until this lands, for anyone hitting the WSOD: pin the previous commit in composer.json — "drupal/viewsreference": "2.x-dev#49b2bc1398a8a272e2364b6ca04fc25645742959".

Thanks both! I had to update the test coverage to be <=11.3 + 10.x compatible to be able to add test coverage for this hence the wider set of changes.
