[Site Isolation] Cross-document view transition should not start after a
cross-origin redirect
https://bugs.webkit.org/show_bug.cgi?id=324578
rdar://187812242
Reviewed by Matt Woodrow.
With Site Isolation enabled, cross-site redirects cause process swaps
mid-navigation. After the process swap, the load starts as a fresh
network load. The new DocumentLoader is unaware of any cross-site
redirects that occurred before.
View Transitions are required not to start if there is a cross-site
redirect somewhere in the load chain.
Track cross-origin redirects on API::Navigation and pass the flag to
whichever process finishes the load.
Remove Navigation::currentRequestIsCrossSiteRedirect(), which is no
longer used.
