This pull request updates and adds some test cases for the split chunks plugin in webpack, which is implemented in the rspack_plugin_split_chunks_new crate. It also simplifies the logic of finding or creating chunks for module groups in the plugin. The main goal is to improve the test coverage and the correctness of the plugin.

• Simplify the logic of finding or creating a chunk for a module group in the split chunks plugin (link)
• Update the import path of the webpack configuration type in the test cases to use the dist folder instead of the root folder (link, link, link)
• Remove the name property from the foo cache group in the test cases to avoid confusion with the chunk name comment in the dynamic import of the foo module (link, link)
• Add a webpack chunk name comment to the dynamic import of the foo module in the test cases to ensure that it creates a separate chunk (link, link, link)
• Update the assertions in the test cases to expect the correct chunks based on the module group name, priority, and reuseExistingChunk option (link, link, link)
• Add a new test case should-not-reuse-existing-chunk-simple-if-cache-group-name-specified with a new webpack configuration file webpack.config.js, a new entry module index.js, and two new modules foo.js and foo-2.js that belong to a cache group named splittedFoo (link, link, link, link)
