[Site Isolation] Defer transitionPageToRemotePage to after BFCache suspension
decision
https://bugs.webkit.org/show_bug.cgi?id=313709
rdar://175905576
Reviewed by Sihui Liu.
During a forward navigation with process swap, delay the
LoadDidCommitInAnotherProcess
IPC and transitionPageToRemotePage() call from
ProvisionalPageProxy::didCommitLoadForFrame()
to WebPageProxy::commitProvisionalPage(), executing them only when BFCache
suspension does
not happen.
A BFCache-suspended page is frozen in the BackForwardCache, not transitioning
to "remote."
Skipping the transition for suspended pages avoids creating a stale
RemotePageProxy that
would later need special cleanup during restoration.
No new tests (no behavior change, feature flag is OFF by default).
