Add webpack's extractLicenses option to rspack's project configuration

[dgmachado]

What problem does this feature solve?

The extractLicenses option can be configured in project.json file and consumed by the Webpack. It's desirable that this option is supported by Rspack.

extractLicenses
Extract all licenses in a separate file, in the case of production builds only.

What does the proposed API of configuration look like?

         "production": {
          "optimization": true,
          "extractLicenses": true,
          "inspect": false,
          "fileReplacements": [
            {
              "replace": "apps/demo-api/src/environments/environment.ts",
              "with": "apps/demo-api/src/environments/environment.prod.ts"
            }
          ]
          "mode": "production",
          "sourceMap": false,
         }
