This PR introduces optional hooks to the scheduler interface for handling `Process.wait`, `Kernel.system` and other related methods (`waitpid`, `wait2`, etc).

It funnels all methods through a new interface `Process::Status.wait` which is almost identical to `Process.wait` except for several key differences:

- The return value is a single instance of `Process::Status`.
- It does not set thread local `$?`.

This is necessary for keeping the scheduler interface simple (and side effects are generally bad anyway).
