  [IFC][Partial layout] Replace a range of damaged line when the new content is PartialFromDamage
https://bugs.webkit.org/show_bug.cgi?id=253651

Reviewed by Antti Koivisto.

When layout produces a subrange of new lines, we need to swap out the old content with this newly constructed one.
Use the existing logic to compute first/last damaged line/box index and swap out the content accordingly.
We also need to update the cached indexes to make sure they all point to the correct boxes.
