layout: Store Fragment results in LayoutBoxBase and start using them for queries (#36583)
Start storing a link to laid-out `Fragment`s in `LayoutBoxBase`, so that
these are accessible for queries and eventually for incremental layout.
Some box tree data structures lacked a `LayoutBoxBase`, such as table
tracks and table track groups[^1].

In addition, start using these `Fragment`s for queries instead of
walking the entire `Fragment` tree. Currently, this isn't possible for
most queries as `Fragment`s do not cache their absolute offsets (which
are often necessary). This change uses the new box tree `Fragment`s for
most resolved style queries.

[^1]: Note that only rows and row groups store `Fragment`s as columsn
and
   colgroups do not produce any.

Testing: This is covered by existing tests.
Fixes: This is part of #36525.
