  WebContent processes should not be able to disable third-party cookie blocking via ApplyTrackingPrevention

Reviewed by Sihui Liu.

This change removes a WebContent -> network process message parameter `ApplyTrackingPrevention` that
allows third-party cookie blocking to be disabled. The conditions that were being checked in the web
process to determine if tracking prevention should be applied should match the network process side
 function that all of these IPC endpoints use (`NetworkStorageSession::shouldBlockCookies`).
