Native image support

[timmattison]

This addresses issue #311.

I have added support for native image that has been tested with GraalVM 22.0.0.2 on Java 17.

The final commit on this PR builds a native image application to print out the operating system name from CRT. This application will build but fail to run without the added configuration. With the new configuration files added it runs as expected.

This has not been tested with every CRT feature so some testing needs to be done to see if the configuration files are complete.

@timmattison this is great - it helped me a lot getting it running. In the meantime there were some new classes added so I had to fix the jni-config. I can confirm this is working for a sample application that writes items to DynamoDB. You can find the full version with the latest CRT Client version here: https://github.com/maschnetwork/aws-lambda-graalvm-crt

Here you can find the updated jni-config and the resource-config which only includes the linux client.

To be able to get the new jni-config I had to do the following things:

1. Clone this repo
2. Install dependencies (cmake) & GraalVM
3. Add an App.class that you provided to be able to execute the native image command
4. Run maven clean package -DskipTests=true to get the uber-jar
5. Run java -agentlib:native-image-agent=config-output-dir=./graal-output -cp target/aws-crt-1.0.0-SNAPSHOT.jar software.amazon.awssdk.crt.App to get the new configs
6. Merge some additional configuration from this PR (e.g. ByteBuffer)
