Improve lazy loading (#12393)

Creating manual chunk was a bad idea, we should always solve lazy
loading problem at the source instance.

Setting a 4.5MB for the index bundle size, CI will fail if we go above.

There is still a lot of room for optimizations!
- More agressive lazy loading (e.g. xyflow and tiptap are still loaded
in index!)
- Add a  prefetch mechanism
- Add stronger CI checks to make sure libraries we've set asides are not
added back
- Fix AllIcons component with does not work as intended (loaded on
initial load)
