feat(common): rename underlying NgFor class and add a type parameter (#14104)

Browse Source 
Note, this affects the underlying class and should not affect usage.

DEPRECATION:
- the `NgFor` class is now deprecated. Use `NgForOf<T>` instead.
  IMPORTANT: Only the `NgFor` class is deprecated, not the `ngFor`
  directive. The `*ngFor` and related directives are unaffected by
  this change  as references to the `NgFor` class generated from
  templates will be automatically converted to references to
  `NgForOf<T>` without requiring any template modifications.
- `TrackByFn` is now deprecated. Use `TrackByFunction<T>` instead.

Migration:
- Replace direct references to the `NgFor` class to `NgForOf<any>`.
- Replace references to `TrackByFn` to `TrackByFunction<any>`.

BREAKING CHANGE:
A definition of `Iterable<T>` is now required to correctly compile
Angular applications. Support for `Iterable<T>` is not required at
runtime but a type definition `Iterable<T>` must be available.

`NgFor`, and now `NgForOf<T>`, already supports `Iterable<T>` at
runtime. With this change the type definition is updated to reflect
this support.

Migration:
- add "es2015.iterable.ts" to your tsconfig.json "libs" fields.
