Remove Profile and policy controlled preferences from incognito whitelist.

Several profile and policy controlled preferences are removed from the
persistent storage list for incognito mode.
As these preferences are not written from inside an incognito window,
the CL is not expected to make any behavioral change and is just
cleanup.
