[Android] Change onTouchEvent to dispatchTouchEvent in `NativeVie…

…wGestureHandler` (#3244)

## Description

Currently wrapping `WebView` into `NativeViewGestureHandler`  doesn't work as expected - events from `native` gesture do not reach `WebView`. This happens because inside `NativeViewGestureHandler` we call `onTouchEvent` method. In native hierarchy `WebView` is nested inside `ViewGroup`, which means that calling `onTouchEvent` instead of `dispatchTouchEvent` won't do anything to the `WebView`.

Should fix #2454 

Fixes #3196 

## Test plan

Tested on example app and the code below:

<details>
<summary>Test code</summary>

```jsx
import * as React from 'react';
import { View, StyleSheet } from 'react-native';
import { WebView } from 'react-native-webview';
import {
  Gesture,
  GestureDetector,
  GestureHandlerRootView,
} from 'react-native-gesture-handler';

function WebViewScreen() {
  const native = Gesture.Native()
    .shouldActivateOnStart(true)
    .disallowInterruption(true);
  const pan = Gesture.Pan().onChange(console.log);

  const g = Gesture.Simultaneous(native, pan);

  return (
    <View style={styles.webViewContainer}>
      <GestureDetector gesture={g}>
        <WebView
          source={{ uri: 'https://templates.tiptap.dev/nw6Cmz6HfD' }}
          style={styles.webView}
          javaScriptEnabled={true}
          domStorageEnabled={true}
          startInLoadingState={true}
          onError={(syntheticEvent) => {
            const { nativeEvent } = syntheticEvent;
            console.warn('WebView error: ', nativeEvent);
          }}
        />
      </GestureDetector>
    </View>
  );
}

export default function BuggyApp() {
  return (
    <GestureHandlerRootView>
      <WebViewScreen />
    </GestureHandlerRootView>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  text: {
    fontSize: 18,
  },
  webView: {
    flex: 1,
  },
  webViewContainer: {
    flex: 1,
    width: '100%',
  },
});
```
