[Site Isolation] Replace parentFrameSecurityOrigin with precomputed bool in
NavigationRequester
https://bugs.webkit.org/show_bug.cgi?id=313181
rdar://175463992
Reviewed by Sihui Liu.
Follows up on https://commits.webkit.org/311805@main by replacing the
RefPtr<SecurityOrigin>
parentFrameSecurityOrigin field with a bool parentOriginIsSameAsTopOrigin.
The origin was only used in
isNavigationBlockedByThirdPartyIFrameRedirectBlocking to check
isSameOriginDomain against the top frame's origin. Since
NavigationRequester already carries topOrigin, precompute the
comparison at capture time in NavigationRequester::from() instead
of carrying a RefPtr<SecurityOrigin>.
No new tests, since this is an optimization.
