Improve bundler size after tree shaking about rspack HOT 7 CLOSED

I have updated the demo and added webpack.

The bundle size of webpack is 73.8 kB, smaller than Rspack, but still larger than Vite/Rollup. Maybe we can align with webpack first.

> rsbuild build --config ./rsbuild.config.webpack.mjs

  Rsbuild v0.3.2

ready   Client compiled in 0.95 s
info    Production file sizes:

  File                                Size       Gzipped    
  dist/index.html                     0.26 kB    0.20 kB
  dist/static/js/index.8effef00.js    73.8 kB    28.9 kB

  Total size:  74.1 kB
  Gzipped size:  29.1 kB

• Rspack: 91.9 kB
• webpack: 73.8 kB
• rollup: 67.83 kB

after enable concatenateModules the size reduced to

Can you try webpack? It would not be considered as a bug, if our bundle size isn't bigger than webpack (at least for current stage).
