Add some comments for VNDK / vendor snapshots
Also some files are refactored:
- snapshot_prebuilt.go is separated from vendor_snapshot.go. Now
vendor_snapshot.go contains snapshot generation codes, while
snapshot_prebuilt.go contains module definition codes.
- Some helper functions are moved from snapshot_utils.go to util.go.
- Some ambiguous names of types and functions are renamed.
We still can add more detailed comments about the snapshots. They are to
be uploaded in follow-up changes, to avoid making this change too big.
Bug: 173474311
Test: generate vndk and vendor snapshot
