>+        When NetworkLoadChecker is freed, make its Content Extension retrieval callback
>+        if any, be called with a cancel error.
>+        Store the callbacks in a map keyed by the NetworkLoadChecker pointer instead of a vector for that purpose.
>+
>+        This allows stopping NetworkLoadChecker be ref counted.
>+        This in turns allows NetworkResourceLoader to delete its NetworkLoadChecker when being deleted as well.
>+        By doing so, we simplify the memory management of NetworkResourceLoader and NetworkLoadChecker.
