This is called after fork before exec to reopen the stdio. We can leverage some abstractions (set blocking, unset cloexec) but musn't call to methods that involve the evloop and would mess with the parent evloop.

Refactors spawning child processes on UNIX that relies on fork/exec to not involve the event loop after fork and before exec. We still continue to rely on the eventloop in the parent process, of course.
Extracted from #14959 that exhibit issues with fork/exec.
