Add _filter_kwargs in ClasswiseWrapper metric wrapper

[ioangatop]

As the ClasswiseWrapper accepts agnostic *args, **kwargs arguments, its not handy to use it in a MetricColletion, as tailored input arguments for other metrics get passed in the metrics.

It would be great, just like in MetricColletion, to add the _filter_kwargs for the metric
