Update test_sys from v3.14.3 and impl more sys module by youknowone · Pull Request #7075 · RustPython/RustPython

- Add sys.call_tracing as func(*args) dispatch
- Add sys._current_exceptions with per-thread exception tracking
  via thread_exceptions registry synced on push/pop/set_exception
- Fix f_back to use previous_frame pointer and cross-thread lookup
- Add module="sys" to float_info struct sequence
- Fix sys.exit to unpack tuple args
- Set default stdio_errors to surrogateescape
- Remove noisy __del__ warning in object core

slot_repr now checks the __module__ attribute set by #[pymodule]
at runtime, so explicit module = "..." in #[pystruct_sequence] is
no longer needed for types defined inside a #[pymodule].
