Fix atomic.wait, get wasi_ctx exit code and thread mgr issues (#2024)

- Remove notify_stale_threads_on_exception and change atomic.wait
  to be interruptible by keep waiting and checking every one second,
  like the implementation of poll_oneoff in libc-wasi
- Wait all other threads exit and then get wasi exit_code to avoid
  getting invalid value
- Inherit suspend_flags of parent thread while creating new thread to
  avoid terminated flag isn't set for new thread
- Fix wasi-threads test case update_shared_data_and_alloc_heap
- Add "Lib wasi-threads enabled" prompt for cmake
- Fix aot get exception, use aot_copy_exception instead
