[3.13] gh-137400: Fix a crash when disabling profiling across all threads (gh-137471) (gh-137649)
The `PyEval_SetProfileAllThreads` function and other related functions
had a race condition on `tstate->c_profilefunc` that could lead to a
crash when disable profiling or tracing on all threads while another
thread is starting to profile or trace a a call.
There are still potential crashes when threads exit concurrently with
profiling or tracing be enabled/disabled across all threads.

[3.13] gh-136914: Fix support of cached functions and properties in DocTest's lineno computation (GH-136930) (GH-137615)
Previously, DocTest's lineno of functions and methods decorated with
functools.cache(), functools.lru_cache() and functools.cached_property()
was not properly returned (None was returned) because the
computation relied on inspect.isfunction() which does not consider the
decorated result as a function.
We now use the more generic inspect.isroutine(), as elsewhere
in doctest's logic.

Replace "ordered arguments" with "positional arguments" in `unittest.mock` documentation (GH-137552)
(cherry picked from commit 64ee1babfb971ddbc00fd8711cccebfbddf6e4ee)
Remove private _PyThreadState and _PyInterpreterState C API
functions: move them to the internal C API (pycore_pystate.h and
pycore_interp.h). Don't export most of these functions anymore, but
still export functions used by tests.
Remove _PyThreadState_Prealloc() and _PyThreadState_Init() from the C
API, but keep it in the stable API.

gh-137463: Update `validate_abstract_methods` in `test_collections.py` (#137464)
Update `validate_abstract_methods` in `test_collections.py`
The test for missing abstract methods in `validate_abstract_methods` incorrectly attempted to instantiate the generated class `C` with an argument (`C(name)`), which always raises a `TypeError: C() takes no arguments`. Although the test originally passes, it passes for the wrong reason.
This change makes the test correctly validate the enforcement of abstract methods in ABCs.

[3.13] GH-133136: Revise QSBR to reduce excess memory held (gh-135473) (gh-136480)
The free threading build uses QSBR to delay the freeing of dictionary
keys and list arrays when the objects are accessed by multiple threads
in order to allow concurrent reads to proceed with holding the object
lock. The requests are processed in batches to reduce execution
overhead, but for large memory blocks this can lead to excess memory
usage.
Take into account the size of the memory block when deciding when to
process QSBR requests.
Also track the amount of memory being held by QSBR for mimalloc pages.
Advance the write sequence if this memory exceeds a limit. Advancing
the sequence will allow it to be freed more quickly.
Process the held QSBR items from the "eval breaker", rather than from
`_PyMem_FreeDelayed()`. This gives a higher chance that the global read
sequence has advanced enough so that items can be freed.

gh-136992: Add "None" as valid `SameSite` value as per RFC 6265bis (GH-137040)
The "SameSite" attribute defined in RFC 6265bis [1] allows the "Strict", "Lax" and "None"
enforcement modes. We already documented "Strict" and "Lax" as being valid values
but "None" was missing from the list. While the RFC has not been formally approved,
modern browsers support the "None" value [2, 3] thereby making sense to document it.
