Summary: This removes some unused flags which will cause Yoga to layout every tree twice, then diffing the tree, reporting whether the whole tree is different. This is too expensive to run outside of local experimentation, but we have more nuanced ways to implement the `YGNodeLayoutAffectedByQuirk` I am wanting to add.
