What's new in this PR?

Issues

Currently, previews for all composables that have some elements which use scoped view models does not work.

Causes (Optional)

It requires to inject a view model using hilt which is not possible for previews.

Solutions

Create annotation @ViewModelScopedPreview to mark all view model interfaces that should have the "preview" object.
These interfaces need to have default implementations.
KSP will generate a "preview" data object with these default implementations and create a list of all "preview" objects for all view model interfaces that are marked with this annotation.
hiltViewModelScoped checks if it's a preview, and if so then it takes a "preview" object, otherwise it injects the proper view model using hilt.
