(cherry picked from commit b5805892d55e769335c11a994b586355720263ba)
When builtin static types are initialized for a subinterpreter, various "tp" slots have already been inherited (for the main interpreter). This was interfering with the logic in add_operators() (in Objects/typeobject.c), causing a wrapper to get created when it shouldn't. This change fixes that by preserving the original data from the static type struct and checking that.

[3.12] Update example of str.split, bytes.split (GH-121287) (#121416)
Update example of str.split, bytes.split (GH-121287)
In `{str,bytes}.strip(chars)`, multiple characters are not treated as a
prefix/suffix, but as individual characters. This may make users confuse
whether `split` has similar behavior.
Users may incorrectly expect that
`'Good morning, John.'.split(', .') == ['Good', 'morning', 'John']`
The tracemalloc_tracebacks hash table has traceback keys and NULL
values, but its destructors do not reflect this -- key_destroy_func is
NULL while value_destroy_func is raw_free. Swap these to free the
traceback keys instead.

[3.12] gh-117983: Defer import of threading for lazy module loading (GH-120233) (GH-121350)
gh-117983: Defer import of threading for lazy module loading (GH-120233)
As noted in gh-117983, the import importlib.util can be triggered at
interpreter startup under some circumstances, so adding threading makes
it a potentially obligatory load.
Lazy loading is not used in the stdlib, so this removes an unnecessary
load for the majority of users and slightly increases the cost of the
first lazily loaded module.
An obligatory threading load breaks gevent, which monkeypatches the
stdlib. Although unsupported, there doesn't seem to be an offsetting
benefit to breaking their use case.
For reference, here are benchmarks for the current main branch:
```
❯ hyperfine -w 8 './python -c "import importlib.util"'
Benchmark 1: ./python -c "import importlib.util"
Time (mean ± σ): 9.7 ms ± 0.7 ms [User: 7.7 ms, System: 1.8 ms]
Range (min … max): 8.4 ms … 13.1 ms 313 runs
```
And with this patch:
```
❯ hyperfine -w 8 './python -c "import importlib.util"'
Benchmark 1: ./python -c "import importlib.util"
Time (mean ± σ): 8.4 ms ± 0.7 ms [User: 6.8 ms, System: 1.4 ms]

Compare to:
```

Add dedicated subsection for `home()`, `expanduser()`, `cwd()`,

keeps all the `Path` constructors (`Path()`, `Path.from_uri()`,
`Path.home()` and `Path.cwd()`) near the top. Within the section, closely
related methods are kept adjacent. Specifically:
- `home()` and `expanduser()` (the former calls the latter)

- `absolute()` and `resolve()` (both make paths absolute)
- `resolve()` and `readlink()` (both read symlink targets)
