Add auth token generator for Amazon Aurora DSQL.

```rust

use aws_sdk_dsql::auth_token::{AuthTokenGenerator, Config};

#[tokio::main]

async fn main() {

   let cfg = aws_config::load_defaults(BehaviorVersion::latest()).await;

   let generator = AuthTokenGenerator::new(

       Config::builder()

           .hostname("peccy.dsql.us-east-1.on.aws")

           .build()

           .expect("cfg is valid"),

   );

   let token = generator.auth_token(&cfg).await.unwrap();

   println!("{token}");

}

```

The resulting token can then be used as a password when connecting to the

database server.

Unnamed enums now validate assigned values and will raise a `ConstraintViolation` if an unknown variant is set.

The following is an example of an unnamed enum:

```smithy

@enum([

    { value: "MONDAY" },

    { value: "TUESDAY" }

])

string UnnamedDayOfWeek

```
