Allow ADO.NET providers to use caller-owned DbDataSource instances as an alternative to connection strings, with provider validation and async connection opening.

ADO.NET providers currently require connection strings, which prevents applications from using provider features such as Npgsql's managed-identity token refresh. This adds a provider-neutral
System.Data.Common.DbDataSourcealternative across clustering, gateway discovery, persistence, reminders, grain directories, and streaming.Each provider now requires exactly one of
ConnectionStringorDataSource. Orleans validates that the data source matches the configured invariant, opens connections asynchronously, disposes each connection after use, and leaves data-source lifetime ownership with the caller or DI container. Existing connection-string configuration remains compatible, including named providers through keyed DI.The change also updates public API baselines and documentation, and adds coverage for validation, ownership, named DI, SQLite persistence, and SQL Server, PostgreSQL, MySQL, and SQLite driver compatibility.
