Debugger hangs when you press stop while an input prompt is active

[rkeithhill]

This is with PSES 0.12.1 and VSCode 1.11.0. Try this. Open a file and put in Remove-Item. This will prompt you for a path to remove. Stop debugging before replying to the prompt in the console. The debugger appears to stop but if you try to debug again, it doesn't start debugging.

Cool, I'll take a look tonight. Aborting the execution should cancel the prompt, but maybe I lost that behavior with the integrated console changes

Seems like there's a larger problem here where input prompts can't be cancelled via code, only through the integrated console. I believe this was caused by my change to using Console.ReadKey synchronously on a background thread. I think it's going to require a loop to check the state of the cancellation token while waiting for the string to be read on a different thread. Not a huge change, but it'll require some testing. Might have to hold off until the next update.
