  Only propagate partitioned cookies setting when tracking prevention is enabled

Reviewed by Charlie Wolfe.

The network process only supports changing the third party cookie blocking mode
when tracking prevention is enabled. We need to keep the blocking mode in the
web processes and network process synchronized, so this patch only propagates
the setting changes if the network process supports it.

Covered by existing tests.
