Feature request: RestartWithBackOffAndFallback for Flow & Sink

Motivation:
I saw in https://github.com/akka/akka/issues/30267 @nvollmar added this feature for actor, but I think it would be nice to have this in pekko-stream, where user can logging the error with a restart/resume, and currently ,we just simply ignore it.

I found the related case from @tg44 in https://discuss.lightbend.com/t/recover-from-sink-exceptions/10554

I think this should be very useful for real production usecase.

Result:
More handy control over the exceptions
