Firebase used to do it automatically (with `cleanUrls: true`), but it
stopped doing it unless the resulting URL corresponds to an existing
file (which is not always the case in angular.io; e.g. the resulting URL
might be matched by a new redirect rule).
This change in Firebase hosting behavior resulted in some URLs not being
correctly redirected (e.g. URLs to the archived v2 site, or `.html`
suffixed URLs from 3rd-party sites).
This commit fixes it, by configuring Firebase hosting to strip off the
`.html` extension and redirect (if no other redirect rule matched).

AIO is currently using a beta version of @angular/service-worker.
Since that was implemented, the SW has been rewritten and released
as part of Angular 5.0.0. This commit updates AIO to use the latest
implementation, with an appropriate configuration file that caches
the various AIO assets in useful ways.

The outdated webpack guide has been removed in #24478, but people might
still try to access it (via direct links or search-engine results).
Instead of returning 404, we will now redirect `/guide/webpack` to the
archived version of the guide at `v5.angular.io/guide/webpack`.

Because:
1. `docs` feels like a "top level" page, similar to `features`, `resources`, `events` etc.
2. This enables the ServiceWorker to pre-fetch/cache the document (similar to what happens with all
other direct children of `content/docs/`), without the need for special-casing it in
`ngsw-manifest.json`.
