Chase Douglas 01da554d7d db: add Aurora DSQL backend
Aurora DSQL speaks a PostgreSQL-compatible wire protocol, but it uses IAM
authentication and has DDL limits that differ from normal PostgreSQL.
Serverless deployments need to select it with a dsql:// DATABASE_URL while
the Diesel layer keeps using the PostgreSQL backend.

Add a dsql feature, classify dsql:// URLs as PostgreSQL, and convert them
to libpq URLs with cached IAM auth tokens. Route DSQL databases through a
dedicated migration set instead of the normal PostgreSQL migrations.

Keep the deployed DSQL migration versions and add DSQL migrations for
upstream schema changes needed by this rebase. Split newer DSQL migrations
into single-DDL, transactionless steps so they can run on Aurora DSQL.
