The `PyThreadState_Clear()` function must only be called with the GIL held and must be called from the same interpreter as the passed in thread state. Otherwise, any Python objects on the thread state may be destroyed using the wrong interpreter, leading to memory corruption. This is also important for `Py_GIL_DISABLED` builds because free lists will be associated with PyThreadStates and cleared in `PyThreadState_Clear()`. This fixes two places that called `PyThreadState_Clear()` from the wrong interpreter and adds an assertion to `PyThreadState_Clear()`.
