Switch to esbuild/Vite builder

Angular 17 switched from Webpack to esbuild/Vite as default builder. Webpack will still be supported for a while but the use of esbuild should lead to significant faster build, so it would make sense to switch.

In a first test building works without issues but there were runtime issues with at least one component (LoadingButtonComponent). Also, Storybook while supporting Vite in general does currently only support Webpack for Angular. Therefore, we have to wait until the whole ecosystem around Angular is ready.
