Currently the template syntax errors are extracted in the template type check phase. But in local compilation mode we skip the type check phase. As a result template syntax errors are not displayed. With this change we show the template syntax diagnostics in local mode.

This commit updates hydration serialization logic to handle a case when the `withI18nSupport()` call is not present for an application that has a component that uses i18n blocks. Note: the issue is only reproducible for components that also inject `ViewContainerRef`, since it triggers a special serialization code path.
Resolves#56074.

When I copied this over in caedd10597
the parentheses moved around the A tag check and the CLICK type check,
instead of around the CLICK and CLICKMOD check.

When a consumer switches its liveness state, it gets added to / removed from
the consumer list of all of its producers. This operation is transitive, so
if its producer is *also* a consumer and *its* liveness state is switched,
then the change is applied recursively.
Note that this only matters *if* the producer is also a consumer. However,
the logic in `producerAddLiveConsumer` / `producerRemoveLiveConsumerAtIndex`
coerced the producer node into a producer & consumer node, which allocated
extra arrays into the node structure that are never used. This didn't affect
correctness, but increased the memory usage of plain signal nodes (which are
just producers, never consumers).
This fix changes the logic in those operations to simply check if a producer
is also a consumer instead of coercing it into one.

This makes events bubble! This change also contains changes to
dispatcher and event_dispatcher to make replay synchronous,
so that we avoid odd timing issues. This can be split out though.
Lastly, we have one cleanup change to move the mapping from
event type to functions on the element itself.

Previously, the event replay serialization logic was located before we verify that a `TNode` exists. `TNode`s may not exist in `tView.data` array in several cases, including cases when there is a local ref used on an element: in this case an extra slot in `LView` contains a reference to the same element and `TNode` is not needed. This commit moves the event replay serialization logic a bit lower, after we check for TNode presence.
Resolves#56073.

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.

Because exhaustive checks traverse the whole tree regardless of the
dirty state, it breaks some expectations around how change detection
should be running. When a view has transplanted views, it
unconditionally marks all ancestors for traversal, assuming this is fine
because the loop will just traverse them and find nothing dirty.
However, exhaustive checkNoChanages actually refreshes everything during
traversal.
This update ensures the exhaustive check only does a single pass and
also prevents some unnecessary marking of transplanted views for
refresh since we know they're going to be reached.
