[3.13] GH-89727: Fix shutil.rmtree() recursion error on deep trees (GH-119808) (#119918)

Browse source 
Implement `shutil._rmtree_safe_fd()` using a list as a stack to avoid emitting recursion errors on deeply nested trees.

`shutil._rmtree_unsafe()` was fixed in a150679f90.

(cherry picked from commit 53b1981fb0)
