Summary: This is a follow up of the work by brentvatne in #5052. This addresses the feedback by astreet. - Uses ReactChoreographer with a new callback type - Callback dispatch logic moved to JS - Only calls into JS when needed, when there are pending callbacks, it even removes the Choreographer listener when no JS context listen for idle events. ** Test plan ** Tested by running a background task that burns all remaining idle time (see new UIExplorer example) and made sure that UI and JS fps stayed near 60 on a real device (Nexus 6) with dev mode disabled. Also tried adding a JS driven animation and it stayed smooth. Tested that native only calls into JS when there are pending idle callbacks. Also tested that timers are executed before idle callback. ``` requestIdleCallback(() => console.log(1)); setTimeout(() => console.log(2), 100); burnCPU(1000); // 2 // 1 ``` I did *not* test with webworkers but it should work as I'm using executor tokens.
