RoleMatrix: allow without AdminBundle

[Hanmac]

Subject

I am targeting this branch, because it should be BC.

Closes #1731.

Changelog

### Changed
- makes references to `service('sonata.admin.pool')` and `service('sonata.admin.configuration')` optional.
- makes references to `service('sonata.user.admin_roles_builder')` and `service('sonata.user.security_roles_builder')` optional.

hmm the null checks are kinda stupid, the functions aren't even called when the pool or configuration is null

@VincentLanglet this MR should be ready?
The Psalm problem is unrelated
and the i can't get the pending tests to run

Yes, we're kinda stuck until #1728 is merged ; @dmaicher is working on it.

yeah I was hoping this could all be done quicker but we are still blocked by external dependencies. This will be fixed in #1730 with adding Symfony 8 compatibility

[dmaicher]

@Hanmac CI was fixed in #1734 just now, Can you rebase?

Only the Symfony 8 job should fail which you can ignore

[dmaicher]

@BadPixxel can you confirm this fixes #1731 for you?

[BadPixxel]

Hi, Many thx for all your efforts! it pass on my side! You can close #1731.

@dmaicher I was thinking about reviving #1519 but that might be for another day 😅
