Added an embedder-controlled web preference to allow privacy-sensitive operations to occur in
non-persistent website data stores. For now this preference is used to control whether media
metadata (e.g., title, artist, artwork) is vended to Now Playing. It may be used in other places in
the future (e.g., when deciding whether privacy-sensitive logging should be allowed).
