Don't establish LayoutState for LayoutTableRow objects.
Table rows are not the containing block of anything. The real containing block
of a table cell is their table section, not the table row.
With this change, we no longer need to pass the object's location to
LayoutState(). Just call locationOffset() on the object in the constructor
instead, rather than doing it at all call sites.
