Currently the migration is set up to assume that any elements that exist in a `declarations` array will be converted to standalone and copied into the `imports` array, however that might be incorrect for some special cases like the root component.
These changes rework the declaration merging logic so that they take all the declarations being migrated into account.
PR Close#48882
Fixes that running the standalone migration with `--defaults` was throwing an error, because all the properties were specified as required. We don't need to set them as required, because they have default values.

Previously, the state `script` was always appended as the last item in the `body` tag. This can result in the state not being available when the Angular application is bootstrap.
A workaround for this was to delay the bootstrapping of the application until by using the `DOMContentLoaded` event listener.
```ts
const bootstrap = () => platformBrowserDynamic().bootstrapModule(AppModule);
document.addEventListener('DOMContentLoaded', bootstrap);
```
With this change the above workaround is no longer necessary as the state `script` tag is now added prior of any other `script` which guarantees that the state is present prior of the Angular application is bootstrapped.

Both TypeScript and Angular Schematic rely on posix system paths which can cause issues on Windows if paths are not normalized correctly.

Currently the `mode` is validated during schematic execution. While this cover a case of incorrect value this caused other parts were the correct values cannot be determined.
Options in schemas are used for a number of reasons during runtime.
- These are used to build auto complete
- Validation of inputs prior of the schematic is built with meaningful errors such as suggested inputs.
- Generation of help output.
Eventually these should also be used to generate DTS. This is already done in the CLI to avoid having to write Types manually.

In order to test components and services which depend on router navigations, such as `ActivatedRoute` instances, tests currently need to provide a fair bit of boilerplate _or_ they can set up a stub for `ActivatedRoute` and list it in the `providers` to override it in `TestBed`. This approach of stubbing the `ActivatedRoute` creates a situation that can easily cause the test to break. The stub often only mocks out the dependencies that the component/service _currently_ needs. This dependencies might change over time and break the test in an unexpected way. In addition, it is difficult to get the structure of `ActivatedRoute` exactly correct.
This change will allow unit tests to quickly set up routes, trigger real navigations in the Router, and get instances of component's to test along with real instances of `ActivatedRoute`. This all comes without needing to know that the component depends on `ActivatedRoute` at all. This becomes more important when considering that a component may be refactored in the future to use `@Input` rather than access data on the `ActivatedRoute` instance (see #18967). Tests which mock out `ActivatedRoute` would all break, but those which use `navigateForTest` would continue to work without needing any updates.

There may be use-cases in the future where `afterNextNavigation` is used
in other locations. For example, a test helper function which navigates
should likely wait for all redirects to complete rather than simply
waiting for the promise returned from `navigate` to resolve.

The main entry point for the `@angular/localize` package no longer imports
the `@angular/compiler` package and now has no external dependencies. This
allows the main functionality of the package to be used without requiring
any other Angular packages. Only the message digest algorithm implementation
from the `@angular/compiler` package was being used and this code is now
bundled directly into the final npm package for `@angular/localize`.
The `tooling` secondary entry point still leverages and requires Angular
related packages (`@angular/compiler`/`@angular/compiler-cli`). However,
the tooling functionality is not intended to be used and/or bundled in
a web application.

Makes the following minor improvements to our current schematic utilities:
* `closestNode` now takes a TS predicate function instead of a `SyntaxKind`. This allows it automatically infer the type of the match.
* `getImportSpecifier` now accepts a regex for the module name. This will be useful for some upcoming migrations.
* Splits the logic for creating the migration program options into a separate function so that it's easier to reuse.
* `createMigrationProgram` now returns the program directly, instead of a literal with some other information.
* `FakeReadFileFn` and `createMigrationCompilerHost` aren't exported anymore since they aren't used anywhere.

The details of this commit are pretty thoroughly described in the tests
and code comments. In short, it is sometimes ambiguous where to apply commands in
a `SegmentGroup` tree that is created from an `ActivatedRoute` when
dealing with empty paths. This adjusts the strategy to tolerate more
ambiguity while still allowing developers to be explicit.

Reworks some of the existing compiler APIs to make them easier to use in a schematic and exposes a few new ones to surface information we already had. High-level list of changes:
* `getPotentialImportsFor` now requires a class reference, instead of a `PotentialDirective | PotentialPipe`.
* New `getNgModuleMetadata` method has been added to the type checker.
* New `getPipeMetadata` method has been added to the type checker.
* New `getUsedDirectives` method has been added to the type checker.
* New `getUsedPipes` method has been added to the type checker.
* The `decorator` property was exposed on the `TypeCheckableDirectiveMeta`. The property was already present at runtime, but it wasn't specified on the interface.

This commit represents rewrite of the NgClass directive to address
severe performance problem (excessive DOM mutation). The modified
algorithm removes all the known performance clifs and has number of
desirable properties:
- it is shorter and (arguably) easier to follow;
- drops usage of existing differs thus limiting dependencies on other
part of the code without increasing size of the directive;
- doesn't degrade any other performance metrics.

The TSLint rule for ESM/CJS interop was apparently not working
for a short period of time due to diverging TypeScript versions.
This commit fixes the lint warning to replace the type-only
import with a default import. Even thoughn not striclty needed
for types- the rule enforces a default import as that is the safer
approach for runtime imported symbols.
Also the rule is updated to not disallow `cluster` anymore. The
types for cluster do no allow for e.g. `cluster.Worker` if cluster
refers to the default import. The whole lint rule is not strictly
needed anymore since we build & test with ESM in this repo now!

`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.
