What's new in this PR?

Issues

We need to support federation search, according to if MLS is enabled, or if it is configured or not in the backend.

Solutions

Create a new use case centralizing the logic to decide if we need to support federation or not for this: team/conversation/backend.

Before the logic was in the view model in AR, but here is centralized and we can test all the cases for it, therefore now the view model just calls this use case to decide if we need to enable cross domain search.

Dependencies (Optional)

A PR will follow in AR.
