layout: Add incremental box tree construction for table caption (#37849)

Browse source 
This change extends incremental box tree updates to table captions. In
addition, calls to `LayoutBox::invalidate_cached_fragment()` are moved
to the damage calculation traversal.

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