Build output total size

[clementmas]

Is it currently possible or would it be a good PR to display the total size of the assets bundled in production?

Something like:

npm run build

vite v4.4.10 building for production...
app.css             20.0 kB
site.css            10.0 kB
app.js              30.0 kB
site.js             15.0 kB
✓ built in Xs
Total: 30.0 KB CSS, 45.0 KB JS

That would help to easily keep an eye on the total size of the assets shipped. Without having to set up custom rules in a CI/CD pipeline.

Thanks!
