LibWeb: Stop refreshing SVG payloads from records at run close

[kalenikaliaksandr]

The close-time refresh compensated for the pass-global used-values store: SVG resource subtrees are laid out once per consumer, and a later consumer's layout rewrote shared records after an earlier placement had already snapshotted them into fragments. Now that runs own their used-values records, each consumer's resource box carries its own slots and every SVG payload write lands before the owning box's placement snapshots it, so the walk never found anything to patch. Delete the refresh and the flag that gated it.

📝 Walkthrough

Walkthrough

The change removes SVG payload-write tracking from RunFragmentBuilder. It deletes tracking state, initialization, notification methods, and close-time recursive payload refreshes. SVG formatting setters no longer notify fragment builders when they update transforms or viewport sizes. SVG path storage also no longer sends a notification.
