The `renderApplication` now also accepts a bootstrapping function call with return `Promise<ApplicationRef>`as the first parameter.
Example:
```ts
const bootstrap = () => bootstrapApplication(RootComponent, appConfig);
const output: string = await renderApplication(bootstrap);

This commits add a utility method to merge multiple `ApplicationConfiguration` into one from left to right. This is useful for server rendering were an application might have several configurations.
Usage Example:
```ts
const config = mergeApplicationConfig(appConfig, appServerConfig);
```

This is needed to provide the merge configuration method which will reside in core.
DEPRECATED: `ApplicationConfig` has moved, please import `ApplicationConfig` from `@angular/core` instead.

This commit moves the `APP_BOOTSTRAP_LISTENER` token into the `application_ref.ts` to avoid a risk of circular dependencies. The main problem is that the token refers to the `ComponentRef`, which in turn refers to more symbols, thus making the `application_tokens.ts` file susceptible to circular dependencies. Such a dependency was identified in https://github.com/angular/angular/pull/49271.

DestroyRef represents a concept of lifecycle scope where destroy
callbacks can be registered. Such callbacks are automatically
executed when a given scope ends it lifecycle.
In practice the most common lifecycle scopes would be represented by:
- a component or en embedded view;
- instance of `EnvironnementInjector`.

This commit moves the `TransferState` class implementation to `@angular/core`. This class will be needed in core in followup changes and `core` can not depend on `platform-browser` package.
The `core` package does **not** export those symbols into public API surface.
The `platform-browser` package re-exports the symbols under same names for backwards-compatibility.

This commit exposes `signal`, `computed`, `effect` and various helpers from
the `@angular/core` entrypoint.
These APIs are marked as `@developerPreview` and are still prototypes in
active development. Their final shapes will be subject to our internal
design reviews as well as one or more community RFCs. We're exporting them
now to allow for experimentation using 16.0.0 next and RC releases.

This commit checks in (but does not export) a prototype implementation of
Angular Signals, along with its unit test suite and a README explaining the
algorithms used.
Signals are not a new concept in the framework space, but there are many
different flavors of implementations. These differ radically both in terms
of public API as well as behavioral details (such as eager vs lazy
computation, batching behavior, equality, cleanup, nesting, etc).
This commit comprises a bespoke implementation that we've designed to best
meet Angular's needs, especially when it comes to compatibility and
flexibility of use within existing applications.
Many of the API features of this implementation of signals, as well as the
larger direction of reactivity in Angular, will be discussed in future RFCs.

While unlikely, prior to this change it was possible to provide a nested array of styles to the render. This required the framework to handle this by doing a flatten operation. This change also renames the `flattenStyles` method as it no longer flattens the styles.
BREAKING CHANGE: `RendererType2.styles` no longer accepts a nested arrays.

`makeEnvironmentProviders` constructs the wrapped `EnvironmentProviders`
type, which can only be used in environment injectors (not element
injectors). It makes sense that `makeEnvironmentProviders` should be able
to accept existing `EnvironmentProviders`-wrapped providers, since it will
be providing the same guarantee, but the current types do not allow this.
This commit fixes the typings to allow nesting `EnvironmentProviders` and
adds a test to verify that it will work.

When injecting the `ChangeDetectorRef` into a node that matches a component, we create a new ref using the component's LView. This breaks down for host directives, because they run before the component's LView has been created.
These changes resolve the issue by creating the LView before creating the node injector for the directives.

This commit removes several debug data structures from
the framework runtime. The data structures in question
were introduced in the framework in the past with the
idea of having debugging aid in the form of the human-redable
data structures. It turned out that in practice those
data structures were not used (most of the fwk developers
didn't even know about their existence!), yet we kept
paying the price of maintaining those duplicated (prod
and debug) version of the data structures.

The useCapture argument of the listener instruction was only
meaningful in the Renderer3 case. Since the Renderer3 code was
removed this argument has no use. Note that we can perform
additional cleanup and remove the useCapture argument from the
listener instruction (this would require change to the instruction
signature, though).

Renderer3 had to store reference to the listener function in order to
properly cleanup event listeners. Since the Renderer3 abstraction was
removed the corresponding code path is no longer needed (Renderer2
returns a cleanup function that can be called directly).

This commit updates the logic related to the attribute and property binding rules for <iframe> elements. There is a set of <iframe> attributes that may affect the behavior of an iframe and this change enforces that these attributes are only applied as static attributes, making sure that they are taken into account while creating an <iframe>.
If Angular detects that some of the security-sensitive attributes are applied as an attribute or property binding, it throws an error message, which contains the name of an attribute that is causing the problem and the name of a Component where an iframe is located.
BREAKING CHANGE:
Existing iframe usages may have security-sensitive attributes applied as an attribute or property binding in a template or via host bindings in a directive. Such usages would require an update to ensure compliance with the new stricter rules around iframe bindings.

This commit updates the logic related to the attribute order on iframes and makes the rules more strict. There is a set of iframe attributes that may affect the behavior of an iframe, this change enforces that these attributes are applied before an `src` or `srcdoc` attributes are applied to an iframe, so that they are taken into account.
If Angular detects that some of the attributes are set after the `src` or `srcdoc`, it throws an error message, which contains the name of ann attribute that is causing the problem and the name of a Component where an iframe is located. In most cases, it should be enough to change the order of attributes in a template to move the `src` or `srcdoc` ones to the very end.
BREAKING CHANGE:
Existing iframe usages may have `src` or `srcdoc` preceding other attributes. Such usages may need to be updated to ensure compliance with the new stricter rules around iframe bindings.

In v14, we've introduced core concepts to allow Components, Directives and Pipes to configure their dependencies
without the need to use NgModules and without the need to be declared in an NgModule. The concepts and initial
set of APIs were marked as "developer preview" to allow developers to use these APIs and share the feedback.
Since v14, we've been reviewing the entire API surface of the framework and either updating existing APIs to support standalone or creating new APIs that allowed to use Router, HttpClient and other abstractions without NgMod
ules.
Based on the mentioned work to review and stabilize APIs and also based on the positive feedback from the commun
ity, we are happy to announce that the Standalone APIs are promoted to stable!
This commit updates vast majority of standalone-related APIs to drop the `@developerPreview` label, which effect
ively documents then as stable.
Two APIs that retained the `@developerPreview` annotations are:
- withRequestsMadeViaParent (from `@angular/common/http`)
- renderApplication (from `@angular/platform-server`)
We plan to collect some additional feedback for the mentioned APIs and drop the `@developerPreview` annotation b
efore the next major release.

This commit introduces a new type `EnvironmentProviders` which can be used
in contexts where Angular accepted `Provider`s destined for
`EnvironmentInjector`s. This includes contexts such as `@NgModule.providers`
and `Route.providers`.
The new type is useful for preventing such providers from accidentally
ending up in `@Component.providers`. It can be used as the return type of
provider functions (such as `provideRouter`) to enforce this safety.
Because `Provider` allows `any[]` nested arrays, the compile-time safety
provided by `EnvironmentProviders` is easily circumvented. However, the
runtime shape of `EnvironmentProviders` is not compatible with component
injectors and will result in a runtime error if it leaks through (NG0207).
A new function `makeEnvironmentProviders` is used to construct this new type
from an array of providers.
The existing `importProvidersFrom` operation previously returned a very
similar type `ImportedNgModuleProviders` which had the same goal. This
machinery is switched over to use the new `EnvironmentProviders` interface
instead (in fact, `ImportedNgModuleProviders` is now just an alias to
`EnvironmentProviders`).
