Remove IServiceProvider

[minichma]

The concept of the IServiceProvider seems overly complex and makes reasoning on the actual control flow hard. It is used for managing IEvaluator instances and for serialization. Remove the use for IEvaluator for now, which already allows removing it from the model types. Keep it for serialization for now and remove it in a subsequent PR.

@axunonb This PR is a tiny step towards decoupling evaluation from the model, following the discussion in #749 (comment).
