In View Engine, providers which neither used `useValue`, `useClass`,
`useFactory` or `useExisting`, were interpreted differently.
e.g.
```
{provide: X} -> {provide: X, useValue: undefined}, // this is how it works in View Engine
{provide: X} -> {provide: X, useClass: X}, // this is how it works in Ivy
```
The missing-injectable migration should migrate such providers to the
explicit `useValue` provider. This ensures that there is no unexpected
behavioral change when updating to v9.

In #33046, internal uses of `zone.js` were switched to reference it
directly from source (built with Bazel) instead of npm. As a result, the
necessary scripts were updated to build `zone.js` as necessary. However,
some `integration/**/debug-test.sh` scripts were missed (apparently
because they are not used on CI, but only locally as helpers for
debugging the integration projects).
This commit updates the `scripts/build-packages-dist.sh` script to also
build `zone.js`, so that other scripts (such as the various
`debug-test.sh` scripts) can use it.

We should not migrate the reference from `useExisting`. This is because
developers can only use the `useExisting` value as a token. e.g.
```ts
@NgModule({
providers: [
{provide: AppRippleConfig, useValue: rippleOptions},
{provide: MAT_RIPPLE_OPTIONS, useExisting: AppRippleConfig},
]
})
export class AppModule {}
```
In the case above, nothing should be decorated with `@Injectable`. The
`AppRippleConfig` class is just used as a token for injection.

Improves the `missing-injectable` migration test case in the
`ng_update_migrations` integration test by adding scenarios
for the recent changes that have been made to the migration.

Updates the Angular CLI version in the `ng_update_migrations`
integration test. Since refactorings are made to the `ng update`
command implementation, we want to make sure that everything
works as expected for the migrations in version 9.
PR Close#33223
Adds a new test to the `ng_update_migrations` that ensures
that the `missing-injectable` migration works properly in a
real CLI project. Additionally this ensures that the
`missing-injectable` and `undecorated-classes-with-di` migrations
play nicely together.
PR Close#32349
Creates anew integratin test for `ng-update` migrations. The
integration test uses an Angular CLI project that will be updated
using the latest package output symlinked from then `./dist/packages-dist`.
This allows us to ensure that migrations work in real CLI projects.
Another big benefit is that the Angular version is updated to the
latest. This is something we couldn't replicate in unit tests but
is extremely important. It's important because compilation could
break with newer Angular versions (note that migrations are always
executed after the new angular version has been installed).
