chore(tvix/store): move NAR rendering logic into Renderer struct
This moves the logic rendering NARs to a struct using the previously introduced, more granular BlobService, ChunkService and DirectoryService. Instead of passing them around to the helper functions, they're kept as members of a struct. Remove the async invocations in the nar_renderer tests, there's nothing async in here.
