Currently we optimize methods that pass both `$index` and the item into a method. We can take this a step further by also optimizing calls that only pass `$index` into the first parameter.

Prior to this commit, event listener options were mutated directly, for example,
`options.signal = undefined` or `options.once = false`.
This issue arises in apps using third-party libraries where the responsibility lies
with the library provider. Some libraries, like WalletConnect, pass an abort controller
as `addEventListener` options. Because the abort controller has the `signal` property,
this is a valid case. Thus, mutating options would throw an error since `signal`
is a readonly property.
Even though zone.js is being deprecated as Angular moves towards zoneless change detection,
this fix is necessary for apps that still use zone.js and cannot migrate to zoneless change
detection because they rely on third-party libraries and are not responsible for the code
used in them.

`EventDispatcher` emulates the browser's event dispatch (mostly).
It supports:
- Bubbling and `stopPropagation`/`stopImmediatePropagation`.
- `currentTarget` during dispatch.
- Throwing errors for `preventDefault` if the event is being dispatched
in replay.
- Throwing errors for `composedPath()` if event is being dispatched in
replay.

This commit updates the `ngswAppInitializer` implementation and removes the `controllerchange`
listener upon the destruction of the `ApplicationRef`. This adjustment aims to prevent memory
leaks. In a zone.js environment, neglecting to do so could lead to the perpetual creation of
a zone task, which captures the zone and obstructs proper garbage collection.

This will prevent running `ActionResolver` logic multiple times while
migrating to use `Dispatcher` to resolve actions rather than
`EventContract`.

The compiler now checks if a signal is properly called on dom property bindings.
The ideal solution would be for the compiler to check if dom property bindings in general are properly typed,
but this is currently not the case, and it is a bigger task to land this change.
In the meantime, the signal diagnostic is augmented to catch cases like the following:
```
<div [id]="mySignal"></div>
```

Users may be using zoneless, but are still loading Zone.js in which case they won't get the full benefits like reduced bundle size. These changes detect such a case and log a warning.

The SecondaryNavigation component was updating state outside of an event handler
without notifying about this change. Modeling state as signal should take
care of proper UI updates (note that I did just a mechanical change here, maybe
there are better ways of dealing with this animations case).

Provide a thorough explanation of why third-party libraries should be created outside
of the Angular zone. Using a statement like "authored with Zone.js in mind" may seem
unusual because third-party libraries typically do not have knowledge of Zone.js, nor
should they be developed with it in mind. Therefore, we revise this explanation accordingly.
Additionally, include a section on handling events originating from third-party APIs.
