@angular/forms declares several directives and a module which are not
exported from the package via the entrypoint, either intentionally or as a
historical accident.
Ivy's locality principle necessitates that directives used in user code be
importable from the package which defines them. This requires these forms
directives to be exported.
Several directives which define ControlValueAccessors are exported:
* NumberValueAccessor
* RangeValueAccessor
A few more directives and a module are exported privately (with a ɵ prefix):
* NgNoValidate
* NgSelectMultipleOption
* InternalFormsSharedModule

Internally getError and hasError call the AbstractControl#get method which takes `path: Array<string | number> | string` as input, since there are different ways to traverse the AbstractControl tree.
This change matches the method signitures of all methods that use this.

This option means guards and resolvers will ignore changes when a provided predicate function returns `false`. This supports use cases where an application needs to ignore some param updates but not others. For example, changing a sort param in the URL might need to be ignored, whereas changing the a `project` param might require re-run of guards and resolvers.

`NgModule` requires that `Component`s/`Directive`s/`Pipe`s are listed in
declarations, and that each `Component`s/`Directive`s/`Pipe` is declared
in exactly one `NgModule`. This change adds runtime checks to ensure
that these sementics are true at runtime.
There will need to be seperate set of checks for the AoT path of the
codebase to verify that same set of semantics hold. Due to current
design there does not seem to be an easy way to share the two checks
because JIT deal with references where as AoT deals with AST nodes.

This option means guards and resolvers will ignore changes to matrix parameters. Guards and resolvers will be rerun when the path changes, when path parameters change, or when query parameters change.
The primary use case for such a mode is when updating the UI and getting the URL to be in sync with local changes. For example, if displaying a sortable table, changing the sort direction is often handled by the table itself. But you would want to update the URL to be in sync with what's being displayed to the user. As long as the table sort direction is stored as a matrix parameter, you can use this option to update the URL without causing the overhead of re-running guards and resolvers.

BREAKING CHANGE:
The public API for `DebugNode` was accidentally too broad. This change removes
1. Public constructor. Since `DebugNode` is a way for Angular to communicate information
on to the developer there is no reason why the developer should ever need to
Instantiate the `DebugNode`
2. We are also removing `removeChild`, `addChild`, `insertBefore`, and `insertChildAfter`.
All of these methods are used by Angular to constructor the correct `DebugNode` tree.
There is no reason why the developer should ever be constructing a `DebugNode` tree
And these methods should have never been made public.
3. All properties have been change to `readonly` since `DebugNode` is used by Angular
to communicate to developer and there is no reason why these APIs should be writable.
While technically breaking change we don’t expect anyone to be effected by this change.

This fixes an issue where a value would hide the type.
```
export interface Foo {
someMethod(): void;
}
export const Foo: Function = ...;
```
In the above example the `Foo` constant will hide the `interface Foo` symbol.
This change properly saves the interface in addition to the type.

A recent commit (probably 2c7386c) has changed the import graph of the
DI types in core, and somehow results in the ngc compiler deciding to
re-export core DI types from application factories which tangentially
use inject(). This is not really surprising; ngc's import graph can be
very unstable.
However, this results in a re-export of InjectFlags surviving JS
compilation. InjectFlags was a const enum, akin to an interface in TS,
with no runtime repesentation. This causes a warning to be emitted by
Webpack when it sees the re-export of InjectFlags.
This commit avoids the issue by removing 'const' from the declaration
of InjectFlags, causing it to have a runtime value. This is a temporary
fix. The real fix will be for ngc to no longer write exports of const
enums.
Testing strategy: manually verified. Due to the problem only manifesting
when recompiling after a change and then running Webpack, there is no
existing framework via which this could be easily tested with an
integration test. Additionally, the potential for this issue is gone in
Ivy, so this solution is only temporarily needed.
Fixes#27251.

Currently, calling `downgradeModule()` more than once is not supported.
If one wants to downgrade multiple Angular modules, they can create a
"super-module" that imports all the rest and downgrade that.
This commit adds support for downgrading multiple Angular modules. If
multiple modules are downgraded, then one must explicitly specify the
downgraded module that each downgraded component or injectable belongs
to, when calling `downgradeComponent()` and `downgradeInjectable()`
respectively.
No modification is needed (i.e. there is no need to specify a module for
downgraded components and injectables), if an app is not using
`downgradeModule()` or if there is only one downgraded Angular module.

These tests are currently broken because of the following reasons:
- ivy no longer emits a generated index, so the filename of the main d.ts file is different
