Add checks for the same instance of handler usage across multiple GestureDetectors

[m-bert]

Description

Some of our users incorrectly use gesture handlers - they pass the same gesture handler instance into multiple GestureDetectors. It very often leads to unexpected behavior, like described in #2688.

Currently web version of our library throws error Handler with tag x already exists. However, there are 2 problems with that:

1. This error message is not really helpful in case of fixing that problem.
2. Native platforms do not perform this check, so people don't know that they're using our handlers in a wrong way.

This PR:

• Improves error message
• Adds check on native platforms
• Adds information about error in GestureDetector documentation in remarks section

Test plan

Tested with code below on all platforms.

Code that throws error

import React from 'react';
import { View } from 'react-native';
import { Gesture, GestureDetector } from 'react-native-gesture-handler';

  export default function Example() {
    const pan = Gesture.Pan();

    return (
      <View>
        <GestureDetector gesture={pan}>
          <View>
            <GestureDetector gesture={pan}>
              <View />
            </GestureDetector>
          </View>
        </GestureDetector>
      </View>
    );
  }
