refactor(common): create an NgFor alias for NgForOf directive

[AndrewKushnir]

This commit adds a re-export of the NgForOf class as NgFor to improve the DX for cases when the directive is used as standalone. Developers can import NgFor class, which better matches the ngFor attribute used in a template.

Should NgFor be the preferred thing for developers to use? If yes, we could update the extended diagnostic for an unknown control flow directive to mention NgFor instead of NgForOf (in KNOWN_CONTROL_FLOW_DIRECTIVES).

@JoostK great point 👍 I've updated the KNOWN_CONTROL_FLOW_DIRECTIVES maps to refer to NgFor instead of NgForOf.
