[3.10] [3.11] gh-99952: fix refcount issues in ctypes.Structure from_param() result (GH-101339) (#101340)

[3.11] gh-99952: [ctypes] fix refcount issues in from_param() result. (GH-100169)

Fixes a reference counting issue with `ctypes.Structure` when a `from_param()` method call is used and the structure size is larger than a C pointer `sizeof(void*)`.

This problem existed for a very long time, but became more apparent in 3.8+ by change likely due to garbage collection cleanup timing changes..
(cherry picked from commit dfad678d7024ab86d265d84ed45999e031a03691)

(cherry picked from commit fa7c37af4936abfe34aa261d6ed9703bc5842ad4)
