Fix bug where absolute nodes were not insetted correctly in certain cases (#1593)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1593

X-link: https://github.com/facebook/react-native/pull/43417

There was a bug where we did not position absolute nodes correctly if the static node had a different main/cross axis from the containing node. This fixes that. The change is somewhat complicated unfortunately but I tried to add sufficient comments to explain what is happening
