Move PolicyHandlers out of handler list factory

Moves
- ForceSafeSearchPolicyHandler
- ForceYouTubeSafetyModePolicyHandler
- BrowsingHistoryPolicyHandler
- SecureOriginPolicyHandler
out of configuration_policy_handler_list_factory.cc to the places that
use the prefs. Merely a cleanup CL - no other changes.
