chore: migrate Spanner to Librarian (googleapis#13184)

Fixes googleapis/librarian#2422 - see that
issue for more details.

From this merge point:

- Generation of API changes will still be automatic, via Librarian
instead of OwlBot
- Releases will be manually initiated: @quartzmo and I will be happy to
pair with the Spanner team for the first release or two
