When querying a Swift module, the scanner now also keeps track of all discovered candidate binary modules which are not compatible with current compilation. - If a Swift dependency is successfully resolved to a compatible binary module or a textual interface, a warning is emitted for every incompatible binary Swift module discovered along the way. - If a Swift dependency is not resolved, but incompatible module candidates were found, an error is emitted - while it is likely that the scan would fail downstream, it is also possible that an underlying Clang module dependency (with the same name) is successfuly resolved and the Swift lookup failure is ignored, which is still going to lead to failures most of the time if the client code assumes the presence of the Swift overlay module in this scenario. This change refactors common error reporting by the scanner into a 'ModuleDependencyIssueReporter' class, which also keeps track of all diagnosed failed lookups to avoid repeating diagnostics.
