  Allow expressing more flavors of third-party cookie blocking

Reviewed by Sihui Liu.

Use an enum instead of a boolean value to describe the current third-party
cookie blocking behavior. Currently, we only support unpartitioned third-party
cookies and they are either allowed or denied. In the future we will support
partitioned third-party cookies, and we will need a tri-state to describe which
kind is allowed: allow unpartitioned and partitioned, allow only partitioned,
deny all third-party cookies.

This patch introduces an enum that describes these three states and uses it
where we currently make decisions about whether third-party cookies are
blocked.

Covered by existing tests.
