Fixed additional patterns that were missed in the initial renaming: - PyThreadState → TyThreadState (typedef and all uses) - PyMem_RawFree → TyMem_RawFree - Py_buffer → Ty_buffer - Py_CLEANUP_SUPPORTED → Ty_CLEANUP_SUPPORTED - PyStatus → TyStatus and PyStatus_NoMemory → TyStatus_NoMemory - _Py__has_builtin → _Ty__has_builtin - _Py_SINGLETON → _Ty_SINGLETON - _Py_CODEUNIT → _Ty_CODEUNIT - _Py_BackoffCounter → _Ty_BackoffCounter - _Py_slot_* and _Py_type_* patterns Build is progressing with fewer errors.
