Workaround solution for: https://github.com/flutter/flutter/issues/121231
See https://github.com/flutter/flutter/issues/120808#issuecomment-1551826299 Error Case 2 for more information.

Sometimes the `ios-deploy` process does not return the logs from the application. We've been unable to figure out why. This is a solution to workaround that by using `idevicesyslog` alongside `ios-deploy` as a backup in getting the log for the Dart VM url. As explained in https://github.com/flutter/flutter/issues/120808#issuecomment-1551826299, when error case 2 happens, the `idevicesyslog` does successfully find the Dart VM.

Also, in the comments of the code it mentions `syslog` is not written on iOS 13+, this was added in response to this issue: https://github.com/flutter/flutter/issues/41133.

However, `idevicesyslog` does in fact work (at least for iOS 16), we use it to collect device logs for our CI tests already: https://github.com/flutter/flutter/blob/1dc26f80f04c1c1091a83c5fead9b3aa83483292/dev/devicelab/lib/framework/devices.dart#L998-L1006
