Add Flow#distinctUntilChanged?

[He-Pin]

Motivation:
I find this pattern in some of our internal codebase, which is more like statefulMap(..).collect{case Some(x) => x} and I find the Kotlin has Flow#distinctUntilChanged too.

  def distinctUtilChanged:Repr[Out] = ???

  def distinctUtilChanged(predicate:(/*old*/ Out, /*new*/ Out) => Boolean):Repr[Out] = ???

That can be done rather easily with statefulMapConcat?

Yes, but still better to have this out of box, let's wait to see if this can accept more votes.
