This change adjusts the E2E schematic to generate a protractor configuration with the selenium promise manager disabled. It also adjusts the generated test files to use native promises and async/await to control test execution.
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
