[BFCache] Remove unused FrameState::hasCachedPage
https://bugs.webkit.org/show_bug.cgi?id=315298
rdar://177631271
Reviewed by Vitor Roriz.
After 313625@main, the WebBackForwardCacheEntry lifecycle is driven by
explicit IPCs (DidCacheItem / DidEvictCachedItem /
DidRestoreFromBackForwardCache) instead of relaying through the
FrameState::hasCachedPage snapshot. The boolean flag has one writer and
zero readers across C++ and Swift; this change removes it.
HistoryItem::isInBackForwardCache() and hasCachedPageExpired() remain.
They are live BackForwardCache queries still used in FrameLoader, the
ShouldGoToBackForwardListItem IPC, and the WebKitLegacy
_isInBackForwardCache / _hasCachedPageExpired SPI.
