Fix exception objects and more Py_ patterns

- Fixed all exception object types: Py*ErrorObject → Ty*ErrorObject
- Fixed Py*ExceptionObject → Ty*ExceptionObject
- Fixed Py*GroupObject, PyStopIterationObject, PySystemExitObject
- Fixed Py_ASNATIVEBYTES_* → Ty_ASNATIVEBYTES_*
- Fixed Py_SAFE_DOWNCAST → Ty_SAFE_DOWNCAST

Build is progressing through more files.
