[3.8] gh-97616: list_resize() checks for integer overflow (GH-97617) (GH-97628)


gh-97616: list_resize() checks for integer overflow (GH-97617)

Fix multiplying a list by an integer (list *= int): detect the
integer overflow when the new allocated length is close to the
maximum size.  Issue reported by Jordan Limor.

list_resize() now checks for integer overflow before multiplying the
new allocated length by the list item size (sizeof(PyObject*)).
(cherry picked from commit a5f092f3)
