[3.13] gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191) (#129217)
gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191)
Support calling PyTraceMalloc_Track() and PyTraceMalloc_Untrack()
during late Python finalization.
* Call _PyTraceMalloc_Fini() later in Python finalization.
* Test also PyTraceMalloc_Untrack() without the GIL
* PyTraceMalloc_Untrack() now gets the GIL.
* Test also PyTraceMalloc_Untrack() in test_tracemalloc_track_race().

[3.13] gh-128679: Fix tracemalloc.stop() race conditions (#128897)
tracemalloc_alloc(), tracemalloc_realloc(), PyTraceMalloc_Track(),
PyTraceMalloc_Untrack() and _PyTraceMalloc_TraceRef() now check
tracemalloc_config.tracing after calling TABLES_LOCK().
_PyTraceMalloc_Stop() now protects more code with TABLES_LOCK(),
especially setting tracemalloc_config.tracing to 1.
Add a test using PyTraceMalloc_Track() to test tracemalloc.stop()
race condition.
Call _PyTraceMalloc_Init() at Python startup.
(cherry picked from commit 6b47499510e47c0401d1f6cca2660fc12c496e39)

gh-121390: tracemalloc: Fix tracebacks memory leak (GH-121391)
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.
(cherry picked from commit db39bc42f90c151b298f97b780e62703adbf1221)
