[internal/aws/awsutil] Refactor : Migrated from AWS Go SDK v1 to v2

NOTE : This PR is not yet fully complete. I created it to seek guidance from the moderators regarding the necessary changes.

Description

This PR migrates the awsutil folder from AWS SDK v1 to v2. Since the internal/aws directory contains several subdirectories that require their own updates, I will be submitting separate PRs for each relevant folder within internal/aws/*. This approach follows the contribution guidelines for a easier review process.

One significant change in this PR is in the GetAWSConfig function. While the arguments passed to the function remain the same, its return value have changed:

• Before: *aws.Config, *session.Session, error
• After: *aws.Config, aws.Config, error

I’d appreciate any feedback on this change and whether it aligns with the expected design.

Link to tracking issue

Fixes #37728 and #36699

Testing

I used the go test -v command to run tests in the internal/aws/awsutil directory. Currently, I have commented out 4 out of 8 test functions due to failures, and I have included comments in the code explaining the reasons for each. I would appreciate guidance on resolving these issues.
