[Site Isolation] Skip SI remote page setup in ProvisionalPageProxy when
restoring from BFCache
https://bugs.webkit.org/show_bug.cgi?id=313760
rdar://175954055
Reviewed by Ryosuke Niwa.
When ProvisionalPageProxy is created from a suspended page (BFCache
restore), skip the Site Isolation remote page infrastructure setup in
initializeWebPage. The suspended page's WebProcess already has the
correct WebPage — setting up remote page parameters or taking an
existing RemotePageProxy is unnecessary and incorrect for this path.
Add a bool isRestoringFromBFCache parameter to initializeWebPage,
set from the presence of a suspendedPage in the constructor.
No new tests (no behavior change, multi-process BFCache feature flag is OFF by
default).
