Subject: ripper: add kwrest_param parser event

* parse.y (f_kwrest): Dispatch kwrest_param event. This is especially
  useful for unnamed kwrest parameter for which we expose the internal
  ID currently.  [ruby-core:75528] [Feature #12387]

* test/ripper/dummyparser.rb (on_kwrest_param): Add handler for
  kwrest_param parser event.

* test/ripper/test_parser_events.rb (test_params): Adapt to the change
  in DummyParser.
  (test_kwrest_param): Test that kwrest_param event handler is called.
