Support resolve.alias for webpack

[mizdra]

ref: https://webpack.js.org/configuration/resolve/#resolvealias

• First, we will implement it for Node.js API users.
  • Use alias option for enhanced-resolve.
• To implement for CLI users, we must consider how to interface.
  • It is difficult to automatically get the value of resolve.alias from webpack.config.js.
  • The webpack configuration file name can be freely changed by the user.
  • In addition, a single configuration file can contain multiple configurations.
  • It might be better to implement CLI options equivalent to webpack-cli's --config and --name options in enhanced-typed-css-modules.
    • i.e. --webpack-config, --webpack-name

Implement here.

If you are using webpack.config.js wrapped with tools such as create-react-app or next.js, I have found that approaches like #96 (comment) don't work.

Perhaps an interface like --webpack-resolve-alias='{"util": "src/util"}' would be better.
