layout: Correct damage propagation and style repair for repaint-only layout (#37004)

When making last-minute changes to the repaint-only layout pass, damage
propagation was broken, meaning that full layout was always done. This
change fixes that, meaning that times in the `blaster.html` test case
now reflect those described in the original commit message from #36978.

In addition, some style repair is now fixed:
- `InlineFormattingContext`s now keep a `SharedInlineStyles` for the
root of the IFC
    which is updated during style repair.
 - `BlockFormattingContext`s now properly update their style.

These changes are verified by turning on repaint only layout for more
properties
in Stylo via servo/stylo#183.

Testing: Manual performance testing via `blaster.html`.
