AWS: Add AWS crt client support

[sullis]

AWS SDK for Java v2
CRT clients

https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/http-configuration-crt.html

From the AWS SDK docs:

The AWS CRT-based HTTP clients provide the following HTTP client benefits:

Faster SDK startup time
Smaller memory footprint
Reduced latency time
Connection health management
DNS load balancing

Amazon announced the CRT HTTP client in February 2023

Ready for review

AWS CRT-based HTTP clients do not use the aws-c-s3 library and do not support the S3 multipart upload API features.

I think this might be an issue if multipart uploads aren't supported

I am planning to continue working on this PR next week. I'll add an update when I have time.
