Fix EZP-22066: Use lazy services whenever possible

https://jira.ez.no/browse/EZP-22066

[EZP-22133](https://jira.ez.no/browse/EZP-22133) made Repository services lazy. This PR intends to remove all *hacks* used to lazy load repository or other sensible services (like ConfigResolver), whenever possible.

##TODO
* [x] Remove usage of `ezpublish.api.repository.lazy`
* [ ] Make `ezpublish.config.resolver` lazy
* [ ] Make `ezpublish_legacy.kernel` lazy
* [ ] Remove `service_container` injection when possible
