[Layout] Fix clusterfuzz DCHECK

We were hitting
DCHECK(HasSetAbsoluteColumnIndex());
when recalculating borders.

Cells do not have AbsoluteColumnIndex set when section needs
cell recalc. Fix is to make section recalc if needed
before computing borders. I am not sure if this will have
any performance implications...

Clusterfuzz is quite elaborate. Several steps are involved in
triggering the bug:
- set needs_cell_recalc on section
- without triggering layout on section, cause child to ask section's
cell to compute its borders.

Figuring a reduced test case would take about a day.
Considering that I am working on eliminating this code completely,
and that this bug has been around forever, I think no test case
is ok.
