Update AnimatedColor-test.js

## Test Plan
Added a comprehensive regression test suite in `packages/react-native/Libraries/Animated/tests/AnimatedColor-test.js` covering:
- Verifying `_listenerCount` does not drop into negative values after a `__detach()` and subsequent `removeListener()` execution.
- Testing `removeListener` safely acts as a no-op when called after `removeAllListeners()`.
- Ensuring native driver subscriptions are properly initiated and systematically torn down without memory leaks during complex component unmount/re-attach lifecycles.
Tested locally by running:
`yarn jest AnimatedColor-test`

## Changelog
[General] [Fixed] - Prevent negative listener count and native subscription memory leaks in AnimatedColor during detach cascades.
