layout: dirty parent node with NodeDamage::ContentOrHeritage when text content changed (#38057)

This change aims to reduce the scope of incremental box tree
construction. Previously, when text content changed, the parent node
would always be marked as requiring box tree reconstruction; now, it is
adjusted to only mark the parent node as needing to recollect its box
tree children.

Testing: This should not change observable behavior and is thus covered
by existing WPT tests.
