  [IFC][Partial layout] Add support for adding/removing line break boxes
https://bugs.webkit.org/show_bug.cgi?id=253292

Reviewed by Antti Koivisto.

Line break box changes (insertion/removal) are going through Invalidation:inlineLevelBoxInserted/inlineLevelBoxWillBeRemoved.
This is similar to what we do when InlineTextBox (RenderText) is inserted/removed (including line damage computation).
