Alex Rickabaugh 3bcf0cf472 fix(service-worker): PushEvent.data has to be decoded (#19764)
PushEvent.data is not the data object itself, but an instance representing
the data in wire format, with methods to synchronously decode it to JSON,
ArrayBuffer, etc. NGSW assumes all push data is in JSON format.

Alex Rickabaugh 396c2417d9 fix(service-worker): freshness strategy should clone response for cache (#19764)
When Cache.put() is called with a Response, it consumes the response. If
the Response is used for any other purpose (such as satisfying the
original FetchEvent) it must be cloned first.

A bug exists in the mocks used for SW tests, where this condition is not
validated. The bodies of MockResponses can be utilized repeatedly without
erroring in the same way that a real browser would. This bug is fixed by
this commit, which causes tests for the freshness strategy of data caching
to start failing.

The cause of this failure is a second bug in the data caching code, where
the Response is not cloned prior to being passed to Cache.put(). This is
also fixed.

Alex Rickabaugh f10f8db5fb fix(service-worker): several misc fixes for corner cases
This commit fixes several issues discovered through use in real apps.

* The sha1() function operated on text content, causing issues for binary-format files.
  A sha1Binary() function which operates on unparsed data now avoids any encoding issues.
* The characters '?' and '+' were not escaped in Glob-to-regex conversion previously, but
  are now.
* URLs from the browser contain the full origin, but were checked against the table of
  hashes from the manifest which only has the path for URLs from the same origin. Now the
  origin is checked and URLs are relativized to the domain root before comparison if
  appropriate.
* ngsw: prefix was missing from data groups, is now added.
* Occasionally servers will return a redirected response for an asset, and caching it could
  cause errors for navigation requests. The SW now handles this by detecting such responses
  and following the redirect manually, to avoid caching a redirected response.
* The request for known assets is now created from scratch from the URL before fetching from
  the network, in order to sanitize it and avoid carrying any special modes or headers that
  might result in opaque responses.
* Debugging log for troubleshooting.
* Avoid creating errors by returning 504 responses on error.
* Fix bug where idle queue doesn't run in some circumstances.
* Add tests for the above.

Alex Rickabaugh d442b6855f feat(service-worker): introduce the @angular/service-worker package (#19274)
This service worker is a conceptual derivative of the existing @angular/service-worker maintained at github.com/angular/mobile-toolkit, but has been rewritten to support use across a much wider variety of applications.

Entrypoints include:

@angular/service-worker: a library for use within Angular client apps to communicate with the service worker.
@angular/service-worker/gen: a library for generating ngsw.json files from glob-based SW config files.
@angular/service-worker/ngsw-worker.js: the bundled service worker script itself.
@angular/service-worker/ngsw-cli.js: a CLI tool for generating ngsw.json files from glob-based SW config files.
