Fixed stale layout when a container resizes after a percentage-based child was measured.

The layout engine's node now records _readsOwnerWidth/_readsOwnerHeight whenever setWidth, setHeight, setMargin, setPadding, or similar methods set a dimension as a percentage. This tracks percent-based width/height dependence for redraw correctness, fixing stale-layout issues when a container's own size changes after a percentage-based child was already measured.
