refactor(tvix/castore/import): restructure error types r/8048

Have ingest_entries return an Error type with only three kinds:

 - Error while uploading a specific Directory
 - Error while finalizing the directory upload
 - Error from the producer

Move all ingestion method-specific errors to the individual
implementations.
