Populate Enterprise Privacy Settings page - batch 1

This CL adds the first batch of items to the Privacy Settings page.
These are all the items that fall into the "What types of
information can your organization see?" category and do not require
deeper Framework changes. Further batches are to come in separate
CLs.

Test: make RunSettingsRoboTests
