Aliaksandr Kalenik 3012c0fe72 LibWeb: Store scroll frames by value in contiguous storage

Replace per-frame heap-allocated RefCounted ScrollFrame objects with a
single contiguous Vector<ScrollFrame> inside ScrollState. All frames for
a viewport are now stored in one allocation, using type-safe
ScrollFrameIndex instead of RefPtr pointers.

This reduces allocation churn, improves cache locality, and moves
parent-chain traversal (cumulative offset, nearest scrolling ancestor)
into ScrollState — similar to how visual context nodes were recently
consolidated into AccumulatedVisualContextTree.
