fixes webpack/webpack#17329
fixes webpack/webpack-cli#3836

Allow to use this, for better DX:

// unknown-loader just for example

//
// For example you can use 
// 
// const needEnablePlugin = process.env.MY_PLUGIN ? true : null;
// `null` can be changed on any `falsy` value, i.e.:
// `false`, `null`, `0`, `""`

module.exports = {
  module: {
    defaultRules: [
      nullValue && {
        test: /\.js$/,
        loader: "unknown-loader",
      },
      "...",
    ],
    rules: [
      nullValue && {
        test: /\.js$/,
        loader: "unknown-loader",
      },
      {
        test: /foo\.js$/,
        oneOf: [
          nullValue && {
            resourceQuery: /inline/,
            loader: "unknown-loader",
          },
          {
            resourceQuery: /external/,
            type: "asset/resource",
          },
        ],
      },
      {
        test: /bar\.js$/,
        use: [nullValue && "unknown-loader"],
      },
      {
        test: /baz\.js$/,
        resourceQuery: /custom-use/,
        use: () => {
          return [
            nullValue && {
              loader: "unknown-loader",
            },
          ];
        },
      },
    ],
  },
  plugins: [
    undefinedValue && new FailPlugin(),
    nullValue && new FailPlugin(),
    falseValue && new FailPlugin(),
    zeroValue && new FailPlugin(),
    emptyStringValue && new FailPlugin(),
  ],
  resolve: {
    plugins: [
      undefinedValue && new FailPlugin(),
    ]
  },
  optimization: {
    minimize: true,
    minimizer: [nullValue && new FailPlugin()],
  },
};
