This adds a new flag used by `flutter analyze --watch` when analyzing the flutter repository. When specified, this flag causes analysis server to enable the public_member_api_docs lint even though it is not enabled in the analysis_options file. `flutter analyze --watch` needs the results of this lint to summarize the number of public members missing dartdoc, but enabling it in the analysis_options causes too much noise in the IDE.
