[WIP] EZP-23704: Added breadcrumbs in admin part

Link: https://jira.ez.no/browse/EZP-23704

## Description
Breadcrumbs for the admin pages.

WORK IN PROGRESS

## Tests
Manual test

## TODO
- [ ] Apply on all template
- [ ] Refactor pjax_admin.html.twig ?

you should not create a translation context specific for the breadcrumbs. For instance, *Section list* in the breadcrumbs or anywhere else in "this page" will be translated the same way.
