Offline Pages - Policy cleanup

This CL adds a client policy bit that controls whether namespaces are
disabled when prefetching-related prefs are disabled.

Also fixes an incorrect policy bit for the NTP articles namespace, it
was set to be cleared on cache when it was in fact a user-requested
data type.

Added some diagnostic information to the policy controller tests.
