This breaks parallel/test-async-wrap-throw-from-callback.

Suggestions on how to keep the changes from #9753 working welcome.

Note: The test parallel/test-async-wrap-throw-from-callback has been deleted in my PR #11883 and this change doesn't affect any other tests.

It makes timers and other libuv handles fire intermittently after the
'exit' event, contrary to what the documentation states.

This change breaks parallel/test-async-wrap-throw-from-callback which I
pragmatically resolved by removing the test.  In all seriousness, it is
scheduled for removal anyway in the upcoming async_wrap revamp so there
isn't much point in sinking a lot of time in it.

It makes timers and other libuv handles fire intermittently after the
'exit' event, contrary to what the documentation states.

Regression introduced in commit aac79df ("src: use stack-allocated
Environment instances") from June last year that made the
`while (handle_cleanup_waiting_ != 0) uv_run(event_loop(), UV_RUN_ONCE)`
loop run unconditionally on exit because it merged CleanupHandles() into
the Environment destructor.

This change breaks parallel/test-async-wrap-throw-from-callback because
the async_wrap idle handle is no longer cleaned up, which I resolved
pragmatically by removing the test.

In all seriousness, it is being removed in the upcoming async_wrap
revamp - it doesn't make sense to sink a lot of time in it now.

I'm assuming/guessing this doesn't need to land on v6.x. Please raise a backport PR if that's not correct.
