fix(@angular-devkit/build-angular): fix aot mode for web worker

[moczix]

i setup angular app in web-worker to use angular DI powers. It all worked well until i build production build. I got error about something bootstrap of undefined. I started investigate angular sources, and found this code.
With aot flag set to false my angularApp inside web-worker with production build doesnt have ivy metadata like "emod".
Comparing this flag to other flags about aot i didnt find out why this flag is set to false. So i made if condition like other places

Hi @moczix,

Thanks for your contribution, however this is the intended behaviour.

Can you please elaborate your use case a bit more to why you need Angular DI in a worker?

Thanks.

@alan-agius4 , i made app similar to your deprecated ui worker thread. But in my case i placed in worker only business logic, and it was cool to have angular DI in worker
