Refactor(@inquirer/core): Streamline exit handlers

[SBoudrias]

Alternative answer to #1536.

2 challenges this code brings:

1. Calling done from a hook cleanup can easily lead to an infinite loop (this code handles it, and there's a unit test covering this case already.)
2. The cycle function becomes a bit more complex - might need to revisit this piece. Looked into extracting it out in #1543
