Preserve the redirect mode when rebuilding asset requests in newRequestWithMetadata(). This keeps explicit redirect:error semantics intact across service-worker redirect handling.
Update the worker test mocks to model redirect defaults correctly and add focused regression coverage for redirected lazy assets with redirect:error.
(cherry picked from commit 07abfbcc6c)
Adds handling and logging for unhandled promise rejections to improve debugging and prevent silent failures. Updates tests and test harness to verify logging of rejection reasons

In this commit, support for `notificationclose` events has been added to the service worker Driver.
When a notification is closed (either by user dismissal or programmatically), the Driver now captures the event, extracts the relevant notification options, and broadcasts a `NOTIFICATION_CLOSE` message to clients. This ensures the application is aware of notification lifecycle events and can react accordingly.

When a new version of app is available in a service worker, and a client with old version exists, web workers initialized from a client with old version will now be properly assigned with the same version.
Before this change, a web worker was assigned with the newest version.

Previously, when requesting non-cached asset resources from the network,
the ServiceWorker would strip off all request metadata (including
headers). This was done in order to avoid issues with opaque responses,
but it turned out to be overly aggressive, breaking/worsening legit
usecases (such as requesting compressed data).
This commit fixes this by preserving the headers of such requests.
For reference, Workbox passes the original request as is. (See for
example the [NetworkFirst][1] strategy).
> **Note**
> Data requests (i.e. requests for URLs that belong to a data-group) are
not affected by this. They already use the original resource as is.

Previously, the `MockServerStateBuilder#withRedirect()` method did two
things: (a) define a redirect from one path to another and (b) specify
the contents of the redirect destination. This was confusing, because it
deviated from the regular way of specifying file contents, which is via
a `MockFileSystem` instance.
This commit slightly simplifies the process of defining redirects by
having the `withRedirect()` method only define the redirect and let the
contents of the redirect destination be specified as usual via
`MockFileSystem`. This makes `MockFileSystem` the single source of truth
for file contents used with `MockServerState`.

Previously, the default value of `MockRequest#credentials` (used in
testing) was set to `omit`. This was different than the default value
used in browsers, which is `same-origin` (see [Request docs on MDN][1])
and could lead to incorrect test results.
This commit changes the default value for `credentials` to `same-origin`
to match what would happen in the browser.

Since the `init` parameter has a default value of `{}`, it can never be

Make the `MockResponse` class used in tests behave more similarly to how
real responses work by making the following improvements:
- Use an empty `statusText` (`''`) when provided, instead of the default
`'OK'` value. This allows better representing opaque responses.
- Preserve more properties (`redirected`, `type`, `url`) when cloning a
`MockResponse`.

Adds support for TypeScript 4.4. High-level overview of the changes made in this PR:
* Bumps the various packages to `typescript@4.4.2` and `tslib@2.3.0`.
* The `useUnknownInCatchVariables` compiler option has been disabled so that we don't have to cast error objects explicitly everywhere.
* TS now passes in a third argument to the `__spreadArray` call inside child class constructors. I had to update a couple of places in the runtime and ngcc to be able to pick up the calls correctly.
* TS now generates code like `(0, foo)(arg1, arg2)` for imported function calls. I had to update a few of our tests to account for it. See https://github.com/microsoft/TypeScript/pull/44624.
* Our `ngtsc` test setup calls the private `matchFiles` function from TS. I had to update our usage, because a new parameter was added.
* There was one place where we were setting the readonly `hasTrailingComma` property. I updated the usage to pass in the value when constructing the object instead.
* Some browser types were updated which meant that I had to resolve some trivial type errors.
* The downlevel decorators tranform was running into an issue where the Closure synthetic comments were being emitted twice. I've worked around it by recreating the class declaration node instead of cloning it.

In the ServiceWorker tests, we use mock implementations of the various

This commit simplifies/systemizes accessing the `CacheStorage` through a
wrapper, with the following benefits:
- Ensuring a consistent cache name prefix is used for all caches
(without having to repeat the prefix in different places).
- Allowing referring to caches using their name without the common
cache name prefix.
- Exposing the cache name on cache instances, which for example makes it
easier to delete caches without having to keep track of the name used
to create them.

The ServiceWorker assigns an app-version to a each client to ensure that
all subsequent requests for a client are served using the same
app-version. The assignment is done based on the client ID.
Previously, the ServiceWorker would only try to read the client's ID off
of the `FetchEvent`'s `clientId` property. However, for navigation
requests the new client's ID will be set on [resultingClientId][1],
while `clientId` will either be empty or hold the ID of the client where
the request initiated from. See also related discussions in
w3c/ServiceWorker#870 and w3c/ServiceWorker#1266.
In theory, this could lead to the navigation request (i.e. `index.html`)
being served from a different app-version than the subsequent
sub-resource requests (i.e. assets). In practice, the likelihood of this
happening is probably very low though, since it would require the latest
app-version to be updated between the initial navigation request and the
first sub-resource request, which should happen very shortly after the
navigation request.
This commit ensures that the correct client ID is determined even for
navigation requests by also taking the `resultingClientId` property into
account.
