`adb` can sometimes hang, which will in turn hang the Dart isolate if we're using `Process.runSync()`. This changes many of the `Device` methods to return `Future<T>` in order to allow them to use the async process methods. A future change will add timeouts to the associated calls so that we can properly alert the user to the hung `adb` process. This is work towards #7102, #9567
