refactor(WebWorker): Make WebWorker bootstrap synchronous

Browse Source 
BREAKING CHANGE

From the app thread, in both TypeScript and Dart, you bootstrap the app
using `application` instead of `asyncApplication`.
Before:
```TypeScript
platform([WORKER_APP_PLATFORM])
.asyncApplication(setupWebWorker, optionalProviders?)
.then((ref) => ref.bootstrap(RootComponent));
```
Now:
```TypeScript
platform([WORKER_APP_PLATFORM])
.application([WORKER_APP_APPLICATION])
.bootstrap(RootComponent);
```
