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.

PR Close#47754
Implements more of the runtime validations for host directives as compiler diagnostics so that they can be caught earlier. Also does some minor cleanup.
PR Close#47768
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`).

This commit modifies `R3Injector` and other code in Angular that deals with

`EnvironmentProviders` as a public feature.

This commit deprecates the above two forms of `providedIn`.
DEPRECATED:
- The ability to pass an `NgModule` to the `providedIn` option for
`@Injectable` and `InjectionToken` is now deprecated.
`providedIn: NgModule` was intended to be a tree-shakable alternative to
NgModule providers. It does not have wide usage, and in most cases is used
incorrectly, in circumstances where `providedIn: 'root'` should be
preferred. If providers should truly be scoped to a specific NgModule, use
`NgModule.providers` instead.
- The ability to set `providedIn: 'any'` for an `@Injectable` or
`InjectionToken` is now deprecated.
`providedIn: 'any'` is an option with confusing semantics and is almost
never used apart from a handful of esoteric cases internal to the framework.

Adds support for host directives on the root component by calling `findHostDirectiveDefs` and passing the results to the relevant functions.
PR Close#47620
The `NgOnChanges` feature matches some legacy ViewEngine behavior where the keys in the `SimpleChanges` object are based on the *declared* names of the inputs, not the public or minified names. This is achieved by constructing the `DirectiveDef.declaredInputs` object at the same time as when `DirectiveDef.inputs` is created.
This logic breaks down for host directives, because they can re-alias the input under a different public name which won't be present in the `declaredInputs`.
These changes add some logic to patch the directive def aliases onto the `declaredInputs`. There is some validation in place to ensure that this patching doesn't overwrite any pre-existing inputs.
PR Close#47597
Adds the logic that will filter out unexposed inputs/outputs and apply the aliases that the author specified when writing the host directives.
