Title: std: Support consuming a Process without waiting

Forking off a child which survives the parent is often a useful task, and is
currently not possible because the Process type will invoke `wait()` in its
destructor in order to prevent leaking resources. This function adds a new safe
method, `daemonize`, which can be used to consume an instance of `Process` which
will then not call `wait` in the destructor.

This new method is clearly documented as a leak of resources, but it must be
forcibly opted in to.

Closes #14467
