refactor(build): use esbuild intead of webpack

Replace `webpack` that went slower with `esbuild`. It significantly reduce the build speed (more
than x20 on my quad core!).

BREAKING CHANGE: The compiler were moved up to the `@whook/whook` project since it was the same for
AWS/GCP and could be reused for other kinds of builds. Also existing project will have to remove
`babel-loader`, `webpack` of dev dependencies and add `esbuild` instead.
