Clean up some search nonIndexableKeys.

- Make the entire gesture setting page unsearchable. This is safe
  because each row in gesture setting page lead to a child page, we are
  only removing duplicates.
- Make the pref controller for System -> gesture return
  AVILABLE_UNSEARCHABLE so it's also suppressed.
- Suppres the parent page for adaptive brightness.
