[3.13] gh-121390: tracemalloc: Fix tracebacks memory leak (GH-121391) (#121392) 

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 db39bc42f9)
