Proper expand definitions for sets (#5676)
In the new view, expandDefinitions is used for eliminating partial operators and is not called during solving, and ppRewrite is called during preprocessing.
For sets, choose is a partial operator that should be applied in expand definitions, and in ppRewrite. On the other hand, is_singleton should not be expanded in expandDefinitions since it is not a partial operator, so it should only be handled in ppRewrite.
It also removes some outdated documentation regarding expandDefinitions with universe set, which is now handled by preventing universe set from occurring in solved substitutions.
This is in preparation for refactoring check-model.
