Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/35315
These headers are needed on react-native-macOS, but not explicitly imported all the time.
It seems that some UIKit header will implicitly import them.
We have other use case in react-native(-iOS) in which we also explicitly importing them - https://github.com/facebook/react-native/search?q=QuartzCore- , hence use following 'that' practice 'here'.
