feat: support module.generator.outputPath

[inottn]

Summary

close #8539

module.generator.outputPath is used to specify the output folder for generated assets. While filename can achieve a similar result, it also modifies the associated URL. For example:

generator: {
  // put emitted files under `assets/*.png`
  // runtime request from `https://xxx/cdn/assets/*.png`
  filename: 'assets/[hash][ext][query]',
  publicPath: 'https://xxx/cdn/'
}

generator: {
  // put emitted files under `assets/*.png`
  // runtime request from `https://xxx/cdn/*.png`
  filename: '[hash][ext][query]',
  outputPath: 'assets'
  publicPath: 'https://xxx/cdn/'
}
