Self-Hosted workbox version

[sidati]

Is your proposal related to a problem?

We need to use a self-hosted version of workbox, we don't want Google to track our traffic 😄

Describe the solution you'd like

Use workbox npm packages

Hm, maybe setting importWorkboxFrom from cdn to local would fix this, at the expense of bundle size.

[sidati]

Yeah @heyimalex, that should do it once this one #5369 is merged, hopefully soon 😅

[silverwind]

Setting local works but that creates the workbox files in its own directory build/workbox-v4.3.1 meaning they are not bundled or cached by the service worker itself which hurts performance.

I'm thinking workbox (and service worker) should be opted-in as a dependency and if present, should be bundled like any other module. Similar to how Sass is also opted in via adding it as a dependency.

This should be closed by #9205, which will go live as part of c-r-a v4.

Thanks @jeffposnick
