Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/36158

To properly setup the Header Search Paths for `use_frameworks!`, we need to move the files that are in the `.../textlayoutmanager/platform/ios` folder into the `.../textlayoutmanager/platform/ios/react/renderer/textlayoutmanager` folder.

This mimic the same folder structure we have also `android`
