Add an `Actor.pformat()`
And map `.__repr__/__str__` to it and add various new fields to fill it out, - drop `self.uid` as var and instead add `Actor._aid: Aid` and proxy to it for the various `.name/.uid/.pid` properties as well as a new `.aid` field. |_ the `Aid.pid` addition is also included. Other improvements, - flip to a sync call to `Address.close_listener()`. - track the `async_main()` parent task as `Actor._task`. - add exception logging around failure to bind due to already-in-use when calling `add.open_listener()` in `._stream_forever()`; sometimes the error might be overridden by something else during the runtime-failure unwind..ns_aware
