[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.
