ASP-based solver: minimize weights over edges (#40632)
With the introduction of multiple build dependencies from the same package in the DAG, we need to minimize a few weights accounting for edges rather than nodes. If we don't do that we might have multiple "optimal" solutions that differ only in how the same nodes are connected together. This commit ensures optimal versions are picked per parent in case of multiple choices for a dependency.
