[Site Isolation] Partition Web process cache entries by main frame site
https://bugs.webkit.org/show_bug.cgi?id=306348
rdar://169014411
Reviewed by Chris Dumez.
When Site Isolation is enabled, we should partition the Web process cache by
main frame site,
so that a cached WebContent process previously used in an iframe cannot be
reused in a later
load where the main frame site is different.
