Implementations of two rxjs-interop APIs which produce `Resource`s from
RxJS Observables. `rxResource()` is a flavor of `resource()` which uses a
projection to an `Observable` as its loader (like `switchMap`).
PR Close#58255
Implement a new experimental API, called `resource()`. Resources are
asynchronous dependencies that are managed and delivered through the signal
graph. Resources are defined by their reactive request function and their
asynchronous loader, which retrieves the value of the resource for a given
request value. For example, a "current user" resource may retrieve data for
the current user, where the request function derives the API call to make
from a signal of the current user id.
Resources are represented by the `Resource<T>` type, which includes signals
for the resource's current value as well as its state. `WritableResource<T>`
extends that type to allow for local mutations of the resource through its
`value` signal (which is therefore two-way bindable).

Currently, `AFTER_RENDER_PHASE_EFFECT_NODE` is not tree-shakable. By wrapping it in an IIFE, it will be annotated as pure, allowing unused code to be removed during the tree-shaking process.
This issue was discovered while investigating: https://github.com/angular/angular-cli/issues/28676.

* Improves handling of the query migration is `strict = false` w/
`strictNullChecks` is configured in the project. There is a special
case that needs to be handled; similar to the input migration.
* Improves readability of the code for normal type generic insertion.
The current logic was a little confusing.

Adds a combined `@angular/core:signals` migration that combines all of the signals-related migrations into one for the apps that want to do it all in one go.
All of the heavy-lifting was already done by the individual migrations, these changes only chain them together for a more convenient developer experience.

xterm was not resizing correctly when terminal/console component was resized.
- Load fitAddon for each terminal instance to enable resize.
- Use `ResizeObserver` to detect changes to the component size changes (window resize does not catch `as-split` events).
- Move padding from `.xterm-screen` to `.xterm` ancestor to fix text alignment.

This change introduces the new reactive primitive: linkedSignal.
A linkedSignal represents state (hence the signal in the name)
that is reset based on the provided computation. Conceptually
it is a state that is maintained / valid only in the context of
another source signal (context is deteremined by a computation).

This commit exposes the new producerMarkClean utility that
makes it possible to mark a reactive node as clean following
changes to the node's value. In practice it resets the dirty
flag and all other internal flags as need. Prior to this change
the cleanup code was duplicated.
The new utility will be used in the linkedSignal implementation.

The `@HostBinding` decorator may be currently applied to inputs
directly, or queries. This is not great and should be replaced with
`host: {}` usages that are more close to template expressions anyway.
Migrating the inputs or queries to signals would break with
`@HostBinding`, because the signals need to be invoked to access their
underlying values. The `@HostBinding` does not do this automatically,
expectedly.

A unit test has been added to check that `EventEmitter` properly completes upon component/directive destrouction when used with `outputToObservable`.
It explains why `destroyRef` has to be injected in `EventEmitter` in the first place.

The keyvalue pipe sorts the entries of the input by key. This has been the subject of debate in the past (https://github.com/angular/angular/issues/42490). The core of the discussions is that it is often desirable (and perhaps expected) that they natural ordering of the input is respected. There are at least two workarounds to restore natural ordering, such as a `compareFn` that simply returns `1` or a custom pipe. However, both of these require code for pipe consumers to maintain or copy around to many places.
Allowing `null` as `compareFn` and treating it as "natural order" is fairly simple to understand, backward compatible and was suggested a few times on https://github.com/angular/angular/issues/42490 where it seemed to be received well. Using `null` is also possible in templates without any component code changes.

BREAKING CHANGE: Angular directives, components and pipes are now standalone by default. Specify for declarations that are currently declared in s. for v19 will take care of this automatically.
Cleans up the logic that was marking a decorator as standalone after some of the recent changes by:
* Reusing some of the existing logic instead of duplicating it.
* Ensuring that we don't drop cases like an explicit `standalone: true`.

Adds the ability to generate the function that replaces the component's metadata during HMR. The HMR update module is a function that is loaded dynamically and as such it has some special considerations:
* It isn't bundled, because doing so will result in multiple version of core.
* Since it isn't bundled, all dependencies have to be passed in as parameters. These changes include some special logic to determine and output those dependencies.
* While HMR is enabled, we have to disable the functionality that generates dynamic imports and drop the dependencies inside `@defer` blocks, because we need to retain the ability to refer to them in case they're needed inside the HMR update function.
* The function is returned by the `NgCompiler` as a string for the CLI's sake.
