Remove dependency of PrefSyncableServiceFactory on //chrome.

Remove dependency of PrefSyncableServiceFactory on //chrome.

Since CommandLinePrefStore will not be moved to syncable_prefs (as it
is tied to the embedder) remove the dependency on it from the factory
and instead requires the client to construct the instance.

Change SetManagedPolicies/SetRecommendedPolicies to take the instance
of policy::BrowserPolicyConnector to remove the dependency on
BrowserProcess.

Update client code after the API changes.
