[3.13] gh-120858: PyDict_Next should not lock the dict (GH-120859) (#120964)
PyDict_Next no longer locks the dictionary in the free-threaded build. Locking
around individual PyDict_Next calls is not sufficient because the function
returns borrowed references and because it allows concurrent modifications
during the iteraiton loop.
The internal locking also interferes with correct external synchronization
because it may suspend outer critical sections created by the caller.
(cherry picked from commit 375b723d5873f948696c7e85a97f4778d9e00ff0)
