Fix: Preserve native animated value after animated component unmount (#28841)

Summary:
After animation has been finished using Native driver there is no final value passed from the native to JS side. This causes a bug from https://github.com/facebook/react-native/issues/28114.

This PR solves this problem in the same way as `react-native-reanimated` library. When detaching it is calling native side to get the last value from Animated node and stores it on the JS side.

Preserving animated value even if animation was using `useNativeDriver: true`
Fixes https://github.com/facebook/react-native/issues/28114
