Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/51512 Pull Request resolved: https://github.com/facebook/react-native/pull/50585 # Changelog: [Internal] Replaces `DOMHighResTimeStamp` alias completely in `ReactCommon` with `HighResTimeStamp`. `DOMHighResTimeStamp` as a type is now expected to be used only in JavaScript. I didn't update places where we explcitly use `std::chrono::high_resolution_clock`, since it is platform-specific and there is no guarantee that `std::chrono::high_resolution_clock` == `std::chrono::steady_clock`. Also, places that are isolated and not part of the Web Performance APIs, such as Telemetry for Fabric, are not updates as part of this diff. Although these subsystems are also using `std::chrono::steady_clock` as a low-level representation, they are not sharing it with other parts of the React Native core.
