Now that the messages in `pkg/front_end/messages.yaml` include `parameters:` entries, support is no longer needed for messages without them. Removing support ensures that we don't accidentally forget to add `parameters:` entries in the future. Additionally, the script `pkg/front_end/tool/add_parameters_to_messages.dart` (which added the `parameters:` entries) is no longer needed.
