What kind of change does this PR introduce?
Part of fix 💎Nice CommonJS modules are converted to ESM and also includes some refactoring to
ExportPropertyLibraryPlugin/ModuleLibraryPlugin.When the entry module is commonjs, we now generate default export pointing to webpack_exports, along with all named exports, aligning with the behavior of cjs-module-lexer.
