FlexChildLayoutCache class
Cache for storing computed layout values for individual flex children.
FlexChildLayoutCache extends the base ChildLayoutCache with flex-specific caching for basis sizes, flex calculations, cross-axis sizing, and baseline alignment. This cache is used to avoid redundant calculations during the complex flex layout algorithm.
