Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/42434 Changelog: [internal] The flags for the event loop were set up using different mechanisms due to the limitations of the previous feature flags systems. Now we can centralize on the new system and use them consistently on Android and iOS. Reviewed By: RSNara Differential Revision: D52819137 fbshipit-source-id: e30a6f2e12b4a027a906502b80a70dd48bb657b6
