RenderMetricsHolder class

Mutable holder for RenderMetrics that WidgetApp updates in-place.

This is intentionally mutable so that metrics can be updated without triggering InheritedWidget notifications. Widgets that read from this holder (e.g. DebugOverlay) pick up the latest value whenever they rebuild for any other reason.
