Add PRIVACY_ADVANCED_SETTINGS intent

Redirect intent actions for PRIVACY_ADVANCED_SETTINGS to the privacy
screen.

Rationale:

1. The existing PRIVACY_SETTINGS intent will later be redirected to
   safety center, but

2. We will still need a way to intent to this screen, because this
   screen will be re-used and renamed to "More privacy settings", also
   known as "Advanced privacy settings"
