I propose to add PyConfig._isolated_interpreter configuration parameter to disallow threads, subprocesses and fork in a subinterpreter.

_xxsubinterpreter.create() gets a new keyword-only isolated=True parameter to opt-in for not isolated mode, which is the current behavior of Py_NewInterpreter(). For example, mod_wsgi would continue to run in "non isolated" mode.

Attached PR implements this change. With the change, os.fork() is allowed again in "non isolated" subinterpreters (like mod_wsgi). os.fork() was disallowed in subinterpreters in Python 3.8, but subprocess was still allowed.
