build: enable noUnusedParameters check

* This enables the "noUnusedParameters" TypeScript option in all tsconfig files. This ensures that every package that will be published can be used together with "noUnusedParameters".
* Added the "noUnusedParameters" option in unrelated tsconfig files as well (gulp tsconfig). This also helps avoiding unused / unnecessary code.
* Skipped setting "noUnusedParameters" for the e2e and prerender project because those are served in AOT mode and the current Angular version of the project does not support "noUnusedParameters" yet.
