Skip tests if no interpreters module.gh-110713 added some tests that use the interpreters module but did not accommodated builds that don't support subinterpreters (incl. an interpreters module). We fix that here by catching ImportError and skipping tests as appropriate.
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.

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.

We tried this before with a dict and for all interned strings. That ran into problems due to interpreter isolation. However, exclusively using a per-interpreter cache caused some inconsistency that can eliminate the benefit of interning. Here we circle back to using a global cache, but only for statically allocated strings. We also use a more-basic _Py_hashtable_t for that global cache instead of a dict.
Ideally we would only have the global cache, but the optional isolation of each interpreter's allocator means that a non-static string object must not outlive its interpreter. Thus we would have to store a copy of each such interned string in the global cache, tied to the main interpreter.

Revert "[3.12] gh-105699: Re-enable the Multiple-Interpreters Stress Tests (gh-107572) (#107783)"
This reverts commit a4aac7d3ea.
The stress tests are still failing on FreeBSD.
This change makes sure sys.path[0] is set properly for subinterpreters. Before, it wasn't getting set at all.
This change does not address the broader concerns from gh-109853.
