Given that #50527 is done, we can finally consume it in ConsoleLifetime.

The goal is to prevent hangs and deadlocks in the most common cases:

This will be on .NET 6 and up only.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Handle SIGTERM in Hosting and handle just like SIGINT (CTRL+C)
280e63e 
Don't listen to ProcessExit on net6.0+ in Hosting anymore. This allows for Environment.Exit to not hang the app.
Don't clobber ExitCode during ProcessExit now that SIGTERM is handled separately.

For non-net6.0 targets, only wait for the shutdown timeout, so the process doesn't hang forever.
