Andrew Ozz 3e36496be3 Privacy: Add an admin pointer for new privacy features in 4.9.6.
The new features are very important for some users, because of their GDPR obligations. They're also spread across multiple top-level menus, making them less discoverable. An admin pointer will help to ensure that users are aware of the new tools and how to find them.

Props desrosj, andreamiddleton, allendav, xkon.
Merges [43158] to the 4.9 branch.
Fixes #43942.
