Web components: Embed translations

[tkohr]

PR adds a EmbeddedTranslateLoader that allows to embed translations in the built js and uses this loader for web components. This prevents the need to ship translation files along with the web component script. For now, it increases the gn-wc.js for about 14 kb per language. At a total size of 4 mb this change seems acceptable to me. Improvements might be made here when we optimize the web component's total bundling size (maybe by including only used translations or lazy loading).

TODO:

• add some doc about web components

Excellent work, clean and simple! I've added a comment to make sure that we don't burden the bundles other than the web component one, but nothing else to add. And kudos for adding so much doc on the web components!!

I'm approving the PR so that you can merge whenever you're done. Thanks 🙂
