crisbeto cf37c003ff feat(ivy): error in ivy when inheriting a ctor from an undecorated base (#34460)
Angular View Engine uses global knowledge to compile the following code:

```typescript
export class Base {
  constructor(private vcr: ViewContainerRef) {}
}

@Directive({...})
export class Dir extends Base {
  // constructor inherited from base
}
```

Here, `Dir` extends `Base` and inherits its constructor. To create a `Dir`
the arguments to this inherited constructor must be obtained via dependency
injection. View Engine is able to generate a correct factory for `Dir` to do
this because via metadata it knows the arguments of `Base`'s constructor,
even if `Base` is declared in a different library.

In Ivy, DI is entirely a runtime concept. Currently `Dir` is compiled with
an ngDirectiveDef field that delegates its factory to `getInheritedFactory`.
This looks for some kind of factory function on `Base`, which comes up
empty. This case looks identical to an inheritance chain with no
constructors, which works today in Ivy.

Both of these cases will now become an error in this commit. If a decorated
class inherits from an undecorated base class, a diagnostic is produced
informing the user of the need to either explicitly declare a constructor or
to decorate the base class.

Pete Bacon Darwin 0b837e2f0d refactor(ngcc): use bundle src to create reflection hosts (#34254)
Previously individual properties of the src bundle program were
passed to the reflection host constructors. But going forward,
more properties will be required. To prevent the signature getting
continually larger and more unwieldy, this change just passes the
whole src bundle to the constructor, allowing it to extract what it
needs.

JoostK 2e5e1dd5f5 refactor(ngcc): rework undecorated parent migration (#33362)
Previously, the (currently disabled) undecorated parent migration in
ngcc would produce errors when a base class could not be determined
statically or when a class extends from a class in another package. This
is not ideal, as it would cause the library to fail compilation without
a workaround, whereas those problems are not guaranteed to cause issues.

Additionally, inheritance chains were not handled. This commit reworks
the migration to address these limitations.

JoostK 31b9492951 feat(ngcc): migrate services that are missing `@Injectable()` (#33362)
A class that is provided as Angular service is required to have an
`@Injectable()` decorator so that the compiler generates its injectable
definition for the runtime. Applications are automatically migrated
using the "missing-injectable" schematic, however libraries built for
older version of Angular may not yet satisfy this requirement.

This commit ports the "missing-injectable" schematic to a migration that
is ran when ngcc is processing a library. This ensures that any service
that is provided from an NgModule or Directive/Component will have an
`@Injectable()` decorator.

George Kalpakas ed70f73794 refactor(ivy): ngcc - remove `formatProperty` from `EntryPointBundle` (#32052)
Remove the `formatProperty` property from the `EntryPointBundle`
interface, because the property is not directly related to that type.

It was only used in one place, when calling `fileWriter.writeBundle()`,
but we can pass `formatProperty` directrly to `writeBundle()`.
