refactor(schematics): group ng-generate schematics in folder (#13794)

* Similarly to the CDK schematics, schematics that can be (ng-)`generated` should be grouped into its own directory. This cleans up the schematics folder and makes it clear where each schematic lives.
* Removes a tslint ignore comment in a schematic test.
