Add persistent cache to CachedStorage::findByPrefix

📌 Add assertions to OpenTelemetryNodePagePerformanceTest::testNodePageCoolCache() Active shows 3 queries from listAll()/findByPrefix(). The mentioned LanguageManager::getLanguages(), which isn't cached and happens early on all pages, field.field.%, which is likely due to loading field config entities and should already be pretty well cached then. And then one for workflows.

Took me a bit of time to debug through the right page to identify those 3. The third is coming from \Drupal\content_translation\Access\ContentTranslationDeleteAccess::checkAccess(), which loads all worfkflows and separately adds them as a cache dependency. That seems unnecessary. If we depend on any of them existing, then this wouldn't cover new ones, and it seems easier and more efficient to just add the list cache tag then.

While stepping through, I also saw a lot of additional lookups. Mostly to check for entity bundles, but also some other stuff, but typically in well cached places. views data for example indirectly triggers a lot of them, like checking if any action config entities exist.

Tempted to won't fix this and instead file two specific issues to add caching to LanguageManager and improve ContentTranslationDeleteAccess

Created 📌 Improve cache dependencies in ContentTranslationDeleteAccess Active

And 📌 Add caching to ConfigurableLanguageManager::getLanguages() Active
