Adds the implementation of the following new instructions:
* `declareLet` - creation-time instruction that initializes the slot for a let declaration.
* `storeLet` - update-time instruction that stores the current value of a let declaration.
* `readContextLet` - instruction that reads the stored value of a let declaration from a different view.
On top of the instructions, it also introduces a new `LetDeclaration` TNode type.
The new TNode is nececessary for DI to work correctly in pipes inside the let expression,
as well as for proper hydration support.

When collecting nodes from the DOM for hydration, we need to treat nodes with paths (e.g. content projection) as the new root for all subsequent elements, not just the next one.
Additionally, when using content projection it's possible for translated content to become disconnected, e.g. when it doesn't match a selector and there isn't a default. We need to handle such cases by manipulating the disconnected node data associated with hydration as usual.

This commit adds extra checks to handle a situation when an application has no events configured, but the Event Replay feature was enabled. This situation can happen when some routes in an application are mostly static, when other routes are more interactive.

These changes integrate let declarations into the template pipeline. This involves a few operations:
* Producing a `declareLet` instruction call at creation time to initialize the declaration.
* Producing a `storeLet` instruction call in the place of the let declaration, including the necessary `advance` calls beforehand.
* For let declarations used within their declaration view, moving the `const` to be placed right after the `storeLet` call to ensure the their value has been computed.
* For let declarations that are _only_ used in their declaration view, removing the `storeLet` call and inlining the expression into the constant statement.

`DOCUMENT` instances retrieved from DI may not contain a necessary function to complete the cleanup. In tests that don't interact with DOM, the `DOCUMENT` might be mocked and some functions might be missing. For such tests, DOM cleanup is not required and we can skip DOM cleanup logic if there are missing functions. For tests that use DOM, TestBed would behave the same as before and rely on more complete `DOCUMENT` instances.

Router's `OutletInjector` required a special handling in cases when `@defer` is used, see https://github.com/angular/angular/pull/55374 for additional info. As a result, the `ChainedInjector` that represents an `OutletInjector` instance is currently exposed via `getInjectorResolutionPath` function. This creates a problem, because other debug APIs used by DevTools can not interact with `ChainedInjector`s. This commit updates the logic around `getInjectorResolutionPath` utility to avoid exposing `OutletInjector`in the resolution path.

This allows for helpers like the following to work intuitively for all
types of "input fields". It also establishes the intended mental
philosophy that a model is both an input and an output.
```ts
/** Unwraps all signal input properties. */
export type UnwrapSignalInputs<T> = {
[K in keyof T]: T[K] extends InputSignalWithTransform<any, infer WriteT>
? WriteT
: T[K];
};

This is related to an issue that was reported internally. We were assuming that `hasNgModuleMetadataElements` will return true only for property assignments initialized to arrays, but that's not the case.
These changes update the type and our assertions to more accurately reflect the AST and to avoid the error.

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.

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.

`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.
