refactor(OutboxDeliveryOptions): abstract base class and method signa…

…ture changes

- Changed `OutboxDeliveryOptions<TDbContext>` to an abstract base class `OutboxDeliveryOptions`.
- Moved the property `MessageTypes` from `OutboxDeliveryOptions<TDbContext>` to the new base class.
- Created a derived class `OutboxDeliveryOptions<TDbContext>` with specific database provider details.
- Updated method signatures in `OutboxExtensions.cs` to use the new base class, removing DbContext dependency where not needed.
