Construct entities from ASSOCIATE, SELECT TYPE, and SELECT RANK are modifiable if the are associated with modifiable variables without vector subscripts. Update WhyNotModifiable() to accept construct entities that are appropriate. A need for more general error reporting from one overload of WhyNotModifiable() caused its result type to change to std::optional<parser::Message> instead of ::MessageFixedText, and this change had some consequences that rippled through call sites. Some test results that didn't allow for modifiable construct entities needed to be updated. Differential Revision: https://reviews.llvm.org/D123722
