`AsyncPipe` would previously promise rejections unhandled and subscription errors uncaught. This is more or less fine in a Zone-based application because errors inside the Angular Zone are caught be the Zone's error trap and reported to `ErrorHandler`. However, in zoneless applications, these errors are never caught or reported by the FW and can reach the node process in SSR and cause it to shut down. BREAKING CHANGE: `AsyncPipe` now directly catches unhandled errors in subscriptions and promises and reports them to the application's `ErrorHandler`. For Zone-based applications, these errors would have been caught by ZoneJS and reported to `ErrorHandler` so the result is generally the same. The change to the exact mechanism for reporting can result in differences in test environments that will require test updates. PR Close #60057
