Ctrl+C of `dotnet run` closes the emulator

[jonathanpeppers]

• On macOS
• dotnet run with no emulator open
• Choose an emulator to run on
• Let the app launch
• Ctrl+C
• The emulator closes! (I'd expect just the app to close)

I think this happens because:

• Terminal sends SIGINT to the process and all child processes
• emulator is a child process and gets closed

Ideally, we'd somehow launch the emulator as not a child process of dotnet run. That way you can't Ctrl+C and close the emulator.

I don't know how that works, if there is an API to do that.
