refactor(WebWorker): Make WebWorker bootstrap synchronous 

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);
```

closes #5857

Closes #5862

Notice how we use the `WORKER_RENDER_APP_COMMON` providers instead of the `WORKER_RENDER_APP` providers on the render thread. Notice how we use the `WORKER_RENDER_APP_COMMON` providers instead of the `WORKER_RENDER_APP` providers on the render thread.
This is because the `WORKER_RENDER_APP` providers include an application initializer that starts a new WebWorker/Isolate. This is because the `WORKER_RENDER_APP` providers include an application initializer that starts a new WebWorker/Isolate.
The `WORKER_RENDER_APP_COMMON` providers make no assumption about where your application code lives. The `WORKER_RENDER_APP_COMMON` providers make no assumption about where your application code lives.
However, we now need to provide our own app initializer. At the very least this initializer needs to call `initializeGenericWorkerRenderer`. However, we now need to provide our own app initializer. At the very least this initializer needs to call `initializeGenericWorkerRenderer`.
This function performs necessary setup work to bootstrap the application.
Similarly we don&amp;t call `setupWebWorker` or `setupIsolate` from the application thread.
Instead we have our own initilization method that sets up our MessageBus and calls `genericWorkerAppProviders`
to finish setting up the application injector.
