[macOS] Switch hasPointerInside to containsPointInView

[m-bert]

Description

While working on LongPress I've noticed that currently check if pointer is inside view is implemented inside NativeViewGestureHandler. I've decided to move it to GestureHandler to be able to use it in other places.

HitSlop

Current implementation of containsPointInView also takes into consideration HitSlop property. The only problem is that on macOS we cannot detect clicks outside of view using mouseDown. This means that HitSlop will work only if click was started inside view - clicking on HitSlop area won't activate handlers.

Test plan

Tested on example app. You can simply see that RectButtons navigate to examples - it doesn't work if pointerInside is false.

Also tested on the following code:

export default function App() {
  return (
    <GestureHandlerRootView style={styles.container}>
      <RectButton style={styles.button} hitSlop={10} onPress={console.log} />
    </GestureHandlerRootView>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'space-around',
    alignItems: 'center',
  },
  button: {
    width: 100,
    height: 30,
    borderRadius: 15,
    backgroundColor: 'crimson',
  },
});
