Add babel plugin to @react-native/babel-preset for console.warn injection under deep react native imports

[coado]

Summary:
The plugin analyses the source of all import, require, and export statements and injects the console.warn statement for each path targeting deep react-native source code. It runs only on a dev mode so there is no need to keep that in the if (__DEV__) block. It is possible to disable this plugin by setting disableDeepImportWarnings: true and resetting the Metro cache:

module.exports = {
  presets: [['module:react-native/babel-preset', {
    "disableDeepImportWarnings": true
  }]],
};

Changelog:
[General][Internal] - Added plugin to react-native/babel-preset injecting console.warn for each react native deep import in dev mode.

For a given code:

import { Image } from 'react-native';
import View from 'react-native/Libraries/Components/View/View';
const Text = require('react-native/Libraries/Text/Text');
export { PressabilityDebugView } from 'react-native/Libraries/Pressability/PressabilityDebug';

The transformed output should look like:

import { Image } from 'react-native';
import View from 'react-native/Libraries/Components/View/View';
const Text = require('react-native/Libraries/Text/Text');
export { PressabilityDebugView } from 'react-native/Libraries/Pressability/PressabilityDebug';
console.warn("Deep imports from the 'react-native' package are deprecated ('react-native/Libraries/Components/View/View').");
console.warn("Deep imports from the 'react-native' package are deprecated ('react-native/Libraries/Text/Text').");
console.warn("Deep imports from the 'react-native' package are deprecated ('react-native/Libraries/Pressability/PressabilityDebug').");

For more information about why this plugin was needed, please check RFC.
