Renames `pkg/analyzer/lib/src/diagnostic/diagnostic.dart` to `pkg/analyzer/lib/src/diagnostic/diagnostic_message.dart`. The new name aligns better with the library's purpose (which is solely to export the class `DiagnosticMessageImpl` from `package:_fe_analyzer_shared`). This frees up the filename `pkg/analyzer/lib/src/diagnostic/diagnostic.dart` to be used as the repository for all generated analyzer messages.
