Martin Robinson 436c9072c4 layout: Skip box tree construction when possible (#37957) ... When a style change does not chang the structure of the box tree, it is possible to skip box tree rebuilding for an element. This change adds support for reusing old box trees when no element has that type of damage. In order to make this happen, there needs to be a type of "empty" `LayoutDamage` that just indicates that a fragment tree layout is necessary. This is the first step toward incremental fragment tree layout. Testing: This should not change observable behavior and thus is covered by existing WPT tests. Performance numbers to follow.
