fix(@angular/cli): add workspace information as part of analytics collection

With this change we collect 3 additional metrics
- `all_projects_count` Count of all project in a workspace
- `libs_projects_count` Count of library projects in a workspace
- `apps_projects_count` Count of application projects in a workspace
