gh-132775: Make _PyXI_session Opaque (gh-134452)
...
This is mostly a refactor to clean things up a bit, most notably the "XI namespace" code.
Making the session opaque requires adding the following internal-only functions:
* _PyXI_NewSession()
* _PyXI_FreeSession()
* _PyXI_GetMainNamespace()

gh-132775: Support Fallbacks in _PyObject_GetXIData() (gh-133482)
...
It now supports a "full" fallback to _PyFunction_GetXIData() and then `_PyPickle_GetXIData()`. There's also room for other fallback modes if that later makes sense.

gh-131185: Use a proper thread-local for cached thread states (gh-132510)
...
Switches over to a _Py_thread_local in place of autoTssKey, and also fixes a few other checks regarding PyGILState_Ensure after finalization.
Note that this doesn't fix concurrent use of PyGILState_Ensure with Py_Finalize; I'm pretty sure zapthreads doesn't work at all, and that needs to be fixed seperately.

cleaned up via _interpreters.destroy. I had to update some of the tests as a result.

This converts functions, code, str, bytes, bytearray, and memoryview objects to PyCodeObject,
and ensure that the object looks like a script. That means no args, no return, and no closure.
_PyCode_GetPureScriptXIData() takes it a step further and ensures there are no globals.
We also add _PyObject_SupportedAsScript() to the internal C-API.

Fix data race detected by tsan
(https://github.com/python/cpython/actions/runs/14857021107/job/41712717208?pr=133502 ):
young.count can be modified by other threads even while the gcstate is
locked.
This is the simplest fix to (potentially) unblock beta 1, although this
particular code path seems like it could just be an atomic swap followed by
an atomic add, without having the lock at all.
