eff3c343b0
Remove Debugger::GetOutputStream and Debugger::GetErrorStream in preparation for replacing both with a new variant that needs to be locked and hence can't be handed out like we do right now. The patch replaces most uses with GetAsyncOutputStream and GetAsyncErrorStream respectively. There methods return new StreamSP objects that automatically get flushed on destruction. See #126630 for more details.
