feat: print a message when the debugee process exits

[jakejx]

This MR makes a simple change to print a message when the debugee process exits. This is useful when debugging a process that is abruptly killed (for e.g. OOM). Currently, it will just look like the process has "hung".

The client already prints something on exit. Is this because of headless instances?

[jakejx]

Hello, yeap the main use case is for headless instances and when --continue is used. I did notice that on MacOS, LLDB does print an exit message. But this does not happen when using dlv on Linux.

Then it needs to work like the maybePrintUnattendedBreakpointWarning (see the call to it below). In fact, it should probably be renamed maybePrintUnattendedStopWarning and be called on both places.

Thanks, let me check those out.

Hi @aarzilli, I have updated the PR with your suggestion. Hopefully I did not misunderstand your suggestion.
