migrate to react-native-reanimated

[vamshi9666]

Current tooltip works great on ios and higher performing devices but not on low end android devices.
Its because animations used currently running on js thread and may slow down on any js process. like an api call or some async task.
To overcome this use useNativeDriver or react-native-reanimated.
As current animation is completely discrete and doesn't depend on gestures and stuff, best way is to use Transition api in reanimated.
