Add full Java module descriptors

### Describe the feature

I'd be great if AWS Java SDK supplied full Java module descriptors.

### Use Case

This will help modular projects that consume the SDK, specifically those that create custom Java Runtimes with jlink, as the latter does not support automatic modules but explicit modules.

### Proposed Solution

It's possible to keep bytecode baseline compatible with Java 8 while providing a full module descriptor thanks to [ModiTect](https://github.com/moditect/moditect).

### Other Information

I've checked all artifacts defined by the [BOM](https://repo1.maven.org/maven2/software/amazon/awssdk/bom/2.20.35/bom-2.20.35.pom) using https://github.com/kordamp/jarviz/ to see if there are any split packages. There are none! 🎉

Most artifacts have an explicit automatic module name via the Automatic-Module-Name manifest attribute, with the following artifacts missing such attribute:
- codegen-lite-maven-plugin-2.20.35.jar
- appsync-2.20.35.jar
- cloudwatch-metric-publisher-2.20.35.jar

Inizia esaminando la AWS SDK BOM e l'elenco degli artefatti segnalati, quindi confronta i metadati dei moduli attuali con i requisiti di ModiTect e jlink. Il lavoro è considerato completato quando gli artefatti SDK dispongono di descrittori di moduli Java espliciti e completi, pur rimanendo compatibili con il bytecode Java 8, inclusi codegen-lite-maven-plugin, appsync e cloudwatch-metric-publisher.
