All TypeScript files have been updated to pass the new eslint-based linting checks. eslint compatible disabling comments have also been added in place of the previous tslint comments.
With this change we remove the requirement to add tsickle as a dependency when having a workspace library.
Since the CTOR downlevel transformer which was previously provided via tsickle is now in ng-packagr version 5.5.1+ We migrate existing libraries to remove the need for tsickle.
