Summary: This is a reconstitution of #24190. It extends accessibility actions to include both a name and user facing label. These extensions support both standard and custom actions. We've also added actions support on Android, and added examples to RNTester showing how both standard and custom accessibility actions are used. ## Changelog [general] [changed] - Enhanced accessibility actions support Pull Request resolved: https://github.com/facebook/react-native/pull/24695 Differential Revision: D15391408 Pulled By: cpojer fbshipit-source-id: 5ed48004d46d9887da53baea7fdcd0e7e15c5739
