Log Message:
-----------
Do not start same-site navigations in a new process
https://bugs.webkit.org/show_bug.cgi?id=303637
Reviewed by Alex Christensen.
This PR makes sure that same site navigations don't get allocated into a new
process, by setting a related page and then comparing the URL to it.
No new tests, but a few progressions.
