The existence of background threads running on a subinterpreter was preventing interpreters from getting properly destroyed, as well as impacting the ability to run the interpreter again. It also affected how we wait for non-daemon threads to finish.

We add PyInterpreterState.threads.main, with some internal C-API functions.

(cherry-picked from commit 1dd9dee)

gh-110707 (0122b4d) added some tests that didn't close file descriptors they created, leading to failures on the refleak buildbots.  This closes the leaking file descriptors, resolving the failure.
