[issue32604] Expose the subinterpreters C-API in Python for testing use.

I'm not seeing any refleak (on linux/clang).  I'm guessing this is Windows-specific (based on use of "./python.exe").  How does test_multiprocessing_fork even run on Windows?  I thought "fork" is an unsupported start method on Windows (see https://docs.python.org/3.7/library/multiprocessing.html#contexts-and-start-methods).

Also, I'm not sure how my change might cause a refleak outside of code using the _xxsubinterpreters module.
