Paul Gschwendtner 349935a434 fix(core): migrations not always migrating all files (#30269)
In an Angular CLI project scenario where projects only reference
top-level source-files through the `tsconfig` `files` option, we currently
do not migrate referenced source-files. This can be fixed checking all
referenced source-files which aren't coming from an external library.

This is similar to how `tslint` determines project source-files.

Injectable annotation on pipes

In ViewEngine it was possible to inject a class that was annotated as a Pipe, however this no longer works in Ivy if the class also doesn't have the Injectable decorator. This migration adds Injectable automatically to all Pipe classes.

Before

import { Pipe } from '@angular/core';

@Pipe({ name: 'myPipe' })
class MyPipe {}

After

import { Pipe, Injectable } from '@angular/core';

@Injectable()
@Pipe({ name: 'myPipe' })
class MyPipe {}
