Currently when using `ivy-ngcc` it will print out a warning
```
Failed to read entry point info from //node_modules/@schematics/angular/workspace/files/package.json with error SyntaxError: Unexpected token < in JSON at position 1121.
```
Fixes#13378
- When using Universal sourceMaps should not be enabled or at least `styles` sourceMaps should be disabled as these will otherwise be inlined and will be set as apart of the server side rendered page.
- While there is no benefit to optimize the scripts at server level, styles should always be minified so that the server side rendered page is smaller.
Fixes#12541 and Fixes#12940
