[cocoa] multiple-cookies partitioned cookies test is a constant failure

Reviewed by Alex Christensen.
This patch fixes two issues.
1) A recent change in the Cooca cookie implementation now requires that
`SameSite=None`
is explicitly specified along with the `Partitioned` cookie attribute. This
patch updates the test and expectations to reflect this change.
2) A recent change within WebKit broke how the preference controlling opt-in
cookie partitioning is propagated to the web content processes. There is a race
condition within which a newly launched web content process may not receive an
updated value when the setting is enabled.
The setting propagation mechanism probably needs to be redesigned, but as a
workaround this patch invalidates the cached preference value whenever we
register a new web process with a datastore.
