  [RenderTreeNeedsLayoutChecker] Add damaged inline display tree check
https://bugs.webkit.org/show_bug.cgi?id=254137

Reviewed by Antti Koivisto.

This checks the unexpected state when
1, inline content is damaged by destroyed renderer(s)
2, we fail to mark the containing block dirty (see webkit.org/b/254090)
3, subsequent layout does not reach the damaged inline content (see #2)
4, inline display content becomes stale
