Disallow thread creation and fork at interpreter finalization.

in the following functions, check if interpreter is finalizing and raise RuntimeError with appropriate message:

  • _thread.start_new_thread and thus threading
  • posix.fork
  • posix.fork1
  • posix.forkpty
  • _posixsubprocess.fork_exec when a preexec_fn= is supplied.

(cherry picked from commit ce558e6)
