…cebook#48878) Summary: Creates a new `scheduleAnimatedCleanupInMicrotask` feature flag to experiment with deferring the `AnimatedProps` cleanup using the microtask queue. This is different from the previous approach of deferring invocation of the completion callback, which impacted the timing of composite animations such as `Animated.parallel` and `Animated.sequence`, because we are deferring detaching the `AnimatedNode` graph instead. This will only impact the timing of completion callbacks as a result of invalidating `AnimatedProps` (either by passing in new `AnimatedValue` instances or unmounting the component). This should minimally impact scheduling and have lower risk of user-visible behavior change because React already provides minimal guarantees around when updates are committed (and effects attached/detached). This also enables us to significantly simplify the current convoluted dance we do to optimized around reference counting in the AnimatedNode graph. Changelog: [General][Changed] - When an Animated component is updated or unmounted, `AnimatedNode` instances will now detach in a microtask instead of synchronously in the commit phase of React. This will cause the completion callback of finished animations to execute after the commit phase instead of during it. Differential Revision: D68527096
