Summary Make WidthCache more generic, preparing for future improvement

As its name implies, WidthCache only caches widths (of given texts, per font). Some code paths (like CanvasRenderingContext2DBase::FontProxy::width() calling FontCascade::width()) also need to compute GlyphOverflow. These could benefit from also caching GlyphOverflow. This preliminary task here will only make WidthCache more generic, to allow the caching of other value types.
