Fix memory leak in AnimatedProps constructor

Removes __attach() call from AnimatedProps constructor that caused
duplicate child additions when combined with lifecycle hook.

The constructor was calling __attach(), then useLayoutEffect in
useAnimatedProps called it again on the same instance, causing each
AnimatedProps to be added as a child twice to its parent nodes.
This led to unbounded memory growth in applications with frequent
re-renders.

This change aligns with React Native core implementation, which does
not call __attach() in the AnimatedProps constructor
