Clean up break-inside restriction propagation from table headers.

Clean up break-inside restriction propagation from table headers.

If a table header has break-inside:avoid, our implementation currently
propagates that to all table rows in the table. Make this more obvious (and
consistent) with a getPaginationBreakability() override in LayoutTableRow,
rather than checking it at only one place (paginationStrutForRow()), although
that may very well have been the only place that needed to care.

No behavioral changes expected.
