PrintJobManagement: Add skeleton code for new PrintJobManagement web app

- This CL includes only the skeleton code to open an empty app from
  chrome://print-management.
- The app and browsertests are in Polymer3.
- Includes basic browsertest to test if app is loaded correctly.
- Future CL will set this app as an System Web App.
- This app is hidden behind a feature flag by default.

Bug: 1053704
Test: browsertest
