Alex Rickabaugh b9a91a5e74 fix(service-worker): don't crash if SW not supported
Currently a bug exists where attempting to inject SwPush crashes the
application if Service Workers are unsupported. This happens because
SwPush doesn't properly detect that navigator.serviceWorker isn't
set.

This change ensures that all passive observation of SwPush and
SwUpdate doesn't cause crashes, and that calling methods to perform
actions on them results in rejected Promises. It's up to applications
to detect when those services are not available, and refrain from
attempting to use them.

To that end, this change also adds an `isSupported` getter to both
services, so users don't have to rely on feature detection directly
with browser APIs. Currently this simply detects whether the SW API
is present, but in the future it will be expanded to detect whether
a particular browser supports specific APIs (such as push
notifications, for example).

Alex Rickabaugh 5adb7c9669 fix(service-worker): listen for messages on the right event source (#19954)
Currently, the SwUpdate service doesn't receive messages from the SW.
This is because it attempts to subscribe to the 'message' event on
ServiceWorkerRegistration, when really messages are emitted by the
ServiceWorkerContainer.

This change moves to listening on ServiceWorkerContainer and changes
the mocks to reflect the way the browser actually works.

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.
