gh-111178: fix UBSan failures in Modules/_ctypes (#129071)
This fixes UBSan failures for the following objects: - `DictRemoverObject` and `StructParamObject`, - `CDataObject` and `CFieldObject`, and - `PyCFuncPtrObject` and `PyCArgObject`. On the default build, we convert the `LOCK_PTR` and `UNLOCK_PTR` macros to functions with an unused parameter to ease "unused variable" compiler warnings suppression. Finally, we also remove some redundant casts to `PyObject *`.
