GH-130397: remove special-casing of C stack depth for WASI ( #134469 )
...
Removed special-casing for WASI when setting C stack depth limits. Since WASI has its own C stack checking this isn't a security risk.
Also disabled some tests that stopped passing. They all happened to have already been disabled under Emscripten.

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()

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.

_PyCode_GetPureScriptXIData() takes it a step further and ensures there are no globals.
We also add _PyObject_SupportedAsScript() to the internal C-API.
