gh-124694: Add concurrent.futures.InterpreterPoolExecutor (gh-124548)

Browse source 
This is an implementation of InterpreterPoolExecutor that builds on ThreadPoolExecutor.

(Note that this is not tied to PEP 734, which is strictly about adding a new stdlib module.)

Possible future improvements:

* support passing a script for the initializer or to submit()
* support passing (most) arbitrary functions without pickling
* support passing closures
* optionally exec functions against __main__ instead of the their original module
