(SB)Target::ConnectRemote doesn't honor synchronous mode

[JDevlieghere]

(SB)Target::ConnectRemote doesn't honor synchronous mode. I looked into this in the past but I don't remember the exact details. The best I could find is a conversation with @jimingham about stopping the private state thread which means that al private events automatically get promoted to public events. This results in a spurious stop event when using lldb-dap and the command finishing before the attach completes on the command line.
