Roll dart_style into the SDK.

I'm still chasing down a couple of google3 failures, but this is ready for review so that I can get it approved and land it once the last couple of failures are fixed. Here is who I think should review what:

athom@ for:

- DEPS

johnniwinther@ for:

- pkg/_fe_analyzer_shared
- pkg/front_end
- pkg/kernel

brianwilkerson@ for:

- pkg/analysis_server
- pkg/analyzer_plugin
- pkg/analyzer_utilities

kenzieschmoll@ for:

- pkg/dartdev

pquitslund@ for:

- pkg/linter/lib/src/lint_codes.g.dart

If you're not the right person, feel free to summon someone else.

Most of the changes here are re-running code generators that auto-format the code they generate. The changes are:

Roll in the latest dart_style commit:

- DEPS

Manually updated these test expectations to expect the new style:

- pkg/analysis_server/test/lsp/format_test.dart
- pkg/analysis_server/test/services/refactoring/agnostic/change_method_signature_test.dart
- pkg/analysis_server/test/src/domains/flutter/set_property_value_test.dart
- pkg/analysis_server/test/src/services/flutter/container_properties_test.dart
- pkg/analysis_server/test/src/services/flutter/widget_descriptions_test.dart
- pkg/analysis_server/test/src/services/refactoring/convert_selected_formal_parameters_to_named_test.dart
- pkg/analysis_server/test/src/services/refactoring/move_selected_formal_parameters_left_test.dart

This was auto-generated by something, but I'm not sure why it thinks there is a diff:

- pkg/analyzer_plugin/doc/api.html

Updated to require a version of dart_style that accepts a language version in DartFormatter():

- pkg/analyzer_plugin/pubspec.yaml

Updated to always use the latest language version (and thus new style) when invoking the formatter:

- pkg/analyzer_utilities/lib/tools.dart

Manually updated the formatting in the code templates so that they matched the formatting expected by the tests, which implicitly format using the latest language version:

- pkg/dartdev/lib/src/templates/...

The rest are all generated files that are formatted so re-generated using the new style:

- pkg/_fe_analyzer_shared/lib/src/experiments/flags.dart
- pkg/_fe_analyzer_shared/lib/src/messages/codes_generated.dart
- pkg/analysis_server_client/lib/handler/notification_handler.dart
