[macOS] Add coordinates to Hover events

[m-bert]

Description

I've noticed that on macOS Hover gesture does not provide coordinates, while on other platforms it does. This PR fixes this mismatch.

import { View } from 'react-native';
import {
  GestureDetector,
  GestureHandlerRootView,
  useHoverGesture,
} from 'react-native-gesture-handler';

export default function App() {
  const hover = useHoverGesture({
    onBegin: (e) => console.log(e),
  });
  return (
    <GestureHandlerRootView>
      <GestureDetector gesture={hover}>
        <View style={{ width: 100, height: 100, backgroundColor: 'red' }} />
      </GestureDetector>
    </GestureHandlerRootView>
  );
}

Pull request overview

This PR updates the macOS implementation of Hover so that hover begin/end events include positional data (x/y and absoluteX/absoluteY), bringing macOS behavior in line with iOS and the JS Hover event payload shape.

Changes:

• Added a macOS helper (extraDataForEvent:) to compute relative and absolute pointer coordinates for hover events.
• Updated mouseEntered: / mouseExited: to send hover state transitions with the computed position extra data instead of pointerInside.
