As discussed in https://bugzilla.mozilla.org/show_bug.cgi?id=1719747#c6, In Part 1, the ownership of the Span in PartsVector is maintained by ICU. This method adds a callback so js::intl::ListFormat could copy the content of the Span to Spidermonkey, and mozilla::intl::ListFormat could use ScopedICUObject to release the string owned by ICU earlier.
