fix(@schematics/angular): remove explicit outputPath option value from generated applications

The `outputPath` option now defaults to `dist/<project_name>` for applications.
This removes the need to explicitly set the option within a newly generated
project. The value removal also reduces the overall size of the `angular.json`
configuration for new projects. Existing projects are not modified by this
change.
