Migrate project to Vite for asset bundling

[vivgui]

The project currently uses webpack for assets bundling but there's an interest in switching to Vite. This PR attempts to do that migration. I first tested this on the foundation theme (you can see my repo fork here) and things worked correctly.

One major thing that the migration to Vite changed is that Vite doesn't use .browserslistrc for setting browser compatibility, it uses esbuild instead so the .config/.browserslistrc file is not needed.

Besides that, I tried my best to replace all the webpack-specific functionality using Vite plugins and configurations.

I know this is a significant change and I'm open to discussing how to best approach it. I just wanted to demonstrate that migrating to Vite is possible and worthwhile.
