[FR]: Provide the AWS CLI 'from source' so it can be used without Rosetta on Apple Silicon

[mattem]

What is the current behavior?

rules_aws uses the packaged distribution for the AWS CLI, which requires Rosetta on Apple silicon, see aws/aws-cli#7252 for more information.

Describe the feature

Provide the AWS CLI as a py_binary target, rather than a native_binary so that it can be used on Apple Silicon without the need for Rosetta.
