API docs: LSIF: emit and store a mapping of documentationResult <-> pathID
Created by: slimsag
This causes us to emit and store a mapping of documentationResult <-> pathID, which allows us to denormalize path IDs (which are often quite long strings) into integers for better storage.
This will be used to implement documentation <-> codeintel interactions.
