Sonu Kapoor 29e8a64cf0 fix(service-worker): by default register the SW after 30s even the app never stabilizes (#35870)
Previously, when using the default ServiceWorker registration strategy
Angular would wait indefinitely for the [app to stabilize][1], before
registering the ServiceWorker script. This could lead to a situation
where the ServiceWorker would never be registered when there was a
long-running task (such as an interval or recurring timeout).

Such tasks can often be started by a 3rd-party dependency (beyond the
developer's control or even without them realizing). In addition, this
situation is particularly hard to detect, because the ServiceWorker is
typically not used during development and on production builds a
previous ServiceWorker instance might be already active.

This commit fixes this by changing the default registration strategy
from `registerWhenStable` to `registerWhenStable:30000`, which will
ensure that the ServiceWorker will be registered after 30s at the
latest, even if the app has not stabilized by then.

Fixes #34464

Sonu Kapoor 00efacf561 feat(service-worker): support timeout in `registerWhenStable` SW registration strategy (#35870)
Previously, when using the `registerWhenStable` ServiceWorker
registration strategy (which is also the default) Angular would wait
indefinitely for the [app to stabilize][1], before registering the
ServiceWorker script. This could lead to a situation where the
ServiceWorker would never be registered when there was a long-running
task (such as an interval or recurring timeout).

Such tasks can often be started by a 3rd-party dependency (beyond the
developer's control or even without them realizing). In addition, this
situation is particularly hard to detect, because the ServiceWorker is
typically not used during development and on production builds a
previous ServiceWorker instance might be already active.

This commit enhances the `registerWhenStable` registration strategy by
adding support for an optional `<timeout>` argument, which guarantees
that the ServiceWorker will be registered when the timeout expires, even
if the app has not stabilized yet.

For example, with `registerWhenStable:5000` the ServiceWorker will be
registered as soon as the app stabilizes or after 5 seconds if the app
has not stabilized by then.

Hoel IRIS 81c2a94310 fix(service-worker): avoid uncaught rejection warning when registration fails (#30876)
Service worker API `navigator.serviceWorker.register` can fail in multiple ways.
For example, in Chrome, with an unstable network connection you can have the
following error: `An unknown error occurred when fetching the script.`

In the current state, it creates an `Uncaught (in promise) TypeError:` style of
error, which cannot be caught by the user on his own.

I think it's better to log the error over raising an error that cannot be
caught.
