gh-103324) We replace _PyRuntime.tstate_current with a thread-local variable. As part of this change, we add a _Py_thread_local macro in pyport.h (only for the core runtime) to smooth out the compiler differences. The main motivation here is in support of a per-interpreter GIL, but this change also provides some performance improvement opportunities. Note that we do not provide a fallback to the thread-local, either falling back to the old tstate_current or to thread-specific storage (PyThread_tss_*()). If that proves problematic then we can circle back. I consider it unlikely, but will run the buildbots to double-check. Also note that this does not change any of the code related to the GILState API, where it uses a thread state stored in thread-specific storage. I suspect we can combine that with _Py_tss_tstate (from here). However, that can be addressed separately and is not urgent (nor critical). (While this change was mostly done independently, I did take some inspiration from earlier (~2020) work by @markshannon (main...markshannon:threadstate_in_tls) and @vstinner (#23976).)

Deep-frozen code objects are cannot be shared (currently) by interpreters, due to how adaptive specialization can modify the bytecodes. We work around this by only using the deep-frozen objects in the main interpreter. This does incur a performance penalty for subinterpreters, which we may be able to resolve later.

This speeds up `super()` (by around 85%, for a simple one-level `super().meth()` microbenchmark) by avoiding allocation of a new single-use `super()` object on each use.
Core static types will continue to use the global value. All other types will use the per-interpreter value. They all share the same range, where the global types use values < 2^16 and each interpreter uses values higher than that.

This is strictly about moving the "obmalloc" runtime state from `_PyRuntimeState` to `PyInterpreterState`. Doing so improves isolation between interpreters, specifically most of the memory (incl. objects) allocated for each interpreter's use. This is important for a per-interpreter GIL, but such isolation is valuable even without it. FWIW, a per-interpreter obmalloc is the proverbial canary-in-the-coalmine when it comes to the isolation of objects between interpreters. Any object that leaks (unintentionally) to another interpreter is highly likely to cause a crash (on debug builds at least). That's a useful thing to know, relative to interpreter isolation.
This PR makes some minor linting adjustments to the Lib/test module caught by [ruff](https://github.com/charliermarsh/ruff). The adjustments are all related to the `F541 f-string without any placeholders` issue.

Use datetime.fromisocalendar in _strptime This unifies the ISO → Gregorian conversion logic and improves handling of invalid ISO weeks.
Using `datetime.datetime.utcnow()` and `datetime.datetime.utcfromtimestamp()` will now raise a `DeprecationWarning`. We also have removed our internal uses of these functions and documented the change.
The prompt will still be incorrect in IDLE on Windows, as IDLE uses CTRL-D for EOF on all platforms.
There were cases where we do unnecessary work for builtin static types. This also simplifies some work necessary for a per-interpreter GIL.
