fix(rust,python): Fix GC logic in write_ipc

[ruihe774]

#17627 changed the logic of maybe_gc(), which was used in write_ipc(). GC might not be performed for arrays with multiple references when writing ipc files, which could result in huge files. This PR fixes it. write_ipc() now decide whether to gc or not based on total_bytes_len() and total_buffer_len().
