[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..
