build: use a separate instance for regular sessions (googleapis#4157)

* build: use a separate instance for regular sessions

Also stop log spamming from Spanner options and reduce the time that a test database
may stay around on a test instance.

* chore: generate libraries at Thu Oct  9 10:12:40 UTC 2025
