[ANDROID TV] Add setNextFocus support

[gregaou]

Add properties to be able to set the nextFocus. It can be very useful with Android TV.

New android View properties :

• nextFocusDown binded to setNextFocusDownId
• nextFocusForward binded to setNextFocusForwardId
• nextFocusLeft binded to setNextFocusLeftId
• nextFocusRight binded to setNextFocusRightId
• nextFocusUp binded to setNextFocusUpId

Can be used to fix :

• Fixes [Android TV] Multiple Scrollviews of Touchable strange D-Pad navigation pattern #20593
• Fixes [Android TV] Adjacent Scrollviews strange D-Pad behaviour at start/end of view #20100

Same PR as #22080 but accorded to changes on master

Test Plan:

I fixed this issue #20100 by doing this

import React, {Component} from 'react';
import {View, Text, TouchableOpacity, ScrollView, findNodeHandle} from 'react-native';

class Item extends Component {
  myRef = null;

  componentDidMount() {
    const { id } = this.props;
    if (id === 0) {
      this.myRef.setNativeProps({ nextFocusLeft:  findNodeHandle(this.myRef)})
    } else if (id === 9) {
      this.myRef.setNativeProps({ nextFocusRight:  findNodeHandle(this.myRef)})
    }
  }

  render() {
    const { id } = this.props;
    return (
      <TouchableOpacity
        key={id}
        ref={(c) => this.myRef = c}
      >
        <View
          style={{
            backgroundColor: 'grey',
            width: 200,
            height: 200,
          }}
        >
          <Text style={{fontSize: 60}}>{id}</Text>
        </View>
      </TouchableOpacity>
    )
  }

}

export default class App extends Component {
  render() {
    const data = [];
    for (let i = 0; i < 10; i++)
      data.push(i);

    return (
      <View>
        {[1, 2].map(() => (
          <ScrollView horizontal style={{height: 210}}>
            {data.map(i => <Item id={i} />)}
          </ScrollView>
        ))}
      </View>
    );
  }
}
