fix(@angular/build): allow top-level await in zoneless applications

With the potential future introduction of features such as WASM/ES module integration
and the experimental chunk optimizer, the need to restrict top-level await
usage is no longer needed and a blocker for new features. As such, top-level
await will now be available if an application has been configured to be
zoneless.
Zoneless Angular is currently experimental and more details can be found here:
