Reland "Make Clear-Site-Data: "cookies" respect third-party cookie blocking"

This is a reland of commit d27d50661e822cb64daec040041b5eabd2642969

Original change's description:

Make Clear-Site-Data: "cookies" respect third-party cookie blocking

This will prevent Clear-Site-Data from being abused for cross-site
tracking 1 when partitioned cookies are enabled by default.

Old behavior: Clear-Site-Data could clear unpartitioned cookies from any context.

New behavior: Clear-Site-Data cannot clear unpartitioned cookies if it came from a response where 3P cookie blocking applies.

In both cases, CSD will delete partitioned cookies in the current partition.

Low-Coverage-Reason:Some files have trial changes that do not impact behavior.
