[issue32363] Deprecate task.set_result() and task.set_exception()

One reason why Task.cancel() is an incomplete replacement for Task.set_exception() is that you don't have an easy way to communicate why the task was ended.

With set_exception() and set_result(), you could. Task.cancel(), though, doesn't let you e.g. specify a CancelledError subclass or "reason" string (see the related bpo-35674, "Add argument to .cancel() of Task and Future").
