strip debugging fprintfs and dead Device.Powered path

Drop the diagnostic logs added during adapter/scan/connect
debugging — the wire flow is now well-understood, so the noise
isn't worth keeping. Also delete iwd_device_set_powered (and the
adapter_obj/adapter_proxy fields it relied on); manager.set_powered
goes through Iwd_Adapter directly, so the device-side fallback is
unreachable.
