[Site Isolation] Clear CORS preflight cache between tests
https://bugs.webkit.org/show_bug.cgi?id=313356

Reviewed by Anne van Kesteren.

Three tests were failing under site isolation because WebKitTestRunner does not clear the CORS preflight cache
in the network process between each test, meaning that CORS preflight from one test bleeds into another.

Added a new mechanism to clear CORS preflight cache for testing purposes and calling it in
TestController::resetStateToConsistentValues.

Co-authored with Claude.

This looks okay, modulo that I'm not 100% sure on the rules for API additions.
