feat: rewrite library state management & related refactor (#5067)

Browse source 
* support libraryItems promise for `updateScene()` and use `importLibrary`

* fix typing for `getLibraryItemsFromStorage()`

* remove `libraryItemsFromStorage` hack

if there was a point to it then I'm missing it, but this part will be rewritten anyway

* rewrite state handling

(temporarily removed loading states)

* add async support

* refactor and deduplicate library importing logic

* hide hints when library open

* fix snaps

* support promise in `initialData.libraryItems`

* add default to params instead
