The AsyncPipe type signature was changed to allow
deferred creation of promises and observalbes that
is supported by the implementation by allowing
`Promise<T>|null|undefined` and by allowing
`Observable<T>|null|undefined`.

This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.
Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".
Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.
Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.
Additionally, this commit adds several unit and integration tests of various
flavors to test this change.

All of the providers in a module get compiled into a module definition in the
factory file. Some of these providers are for the actual module types, as those
are available for injection in Angular. For tree-shakeable tokens, the runtime
needs to be able to distinguish which modules are present in an injector.
This change adds a NodeFlag which tags those module providers for later
identification.

This is because the CompilerOptions needs to have directoryExists undefined in order to get the google3 behavior,
so we have to set the property outside the constructor.

Both Firefox and Safari are vulnerable to XSS if we use an inert document
created via `document.implementation.createHTMLDocument()`.
Now we check for those vulnerabilities and then use a DOMParser or XHR
strategy if needed.
Further the platform-server has its own library for parsing HTML, so we
sniff for that (by checking whether DOMParser exists) and fall back to
the standard strategy.
Thanks to @cure53 for the heads up on this issue.

The `ng_module` rule now has a factories attribute that
allows explicit specification of which files are expected
to generate factories. This allows avoiding generating
empty factory files (such as `.ngfactory.js`) begin
generated which might cause down-stream tools issues if
they have a limit on the number of files that can be
processed in a single bazel action.

Previously, the emitEvent flag was only checked when emitting on the current control.
Thus, if the control was part of a hierarchy, events were emitted on the parent and the childrens.
This fixes the issue by properly passing the emitEvent flag to both parent and childrens.

Service Workers can be tricky to work with in production, and often
it becomes necessary to deactivate an existing SW. This is trickier
than one might imagine - as long as clients on the old SW may exist
it is important to serve some script at the old SW URL. This commit
adds safety-worker.js to the published NPM package, which is useful
for that purpose. On install the SW unregisters itself which safely
and gradually allows older clients to update.

Previously, an interceptor attempting to inject HttpClient directly
would receive a circular dependency error, as HttpClient was
constructed via a factory which injected the interceptor instances.
Users want to inject HttpClient into interceptors to make supporting
requests (ex: to retrieve an authentication token). Currently this is
only possible by injecting the Injector and using it to resolve
HttpClient at request time.
Either HttpClient or the user has to deal specially with the circular
dependency. This change moves that responsibility into HttpClient
itself. By utilizing a new class HttpInterceptingHandler which lazily
loads the set of interceptors at request time, it's possible to inject
HttpClient directly into interceptors as construction of HttpClient no
longer requires the interceptor chain to be constructed.
Fixes#18224.
