EZP-23704: Added breadcrumbs in admin part

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

it would be nice to handle a breadcrumbs level without link for 3 reasons:
1. `#` might cause issues in the PlatformUI JS application if the user clicks on this link
2. an element in the breadcrumb might not be reachable with a simple link while it's still part of the structure
3. the last element of the breadcrumbs should not be a link since it's the page where you are already
