ASP-based solver: single Spec instance per dag hash (#39590)
Reused specs used to be referenced directly into the built spec. This might cause issues like in issue 39570 where two objects in memory represent the same node, because two reused specs were loaded from different sources but referred to the same spec by DAG hash. The issue is solved by copying concrete specs to a dictionary keyed by dag hash.
