Refactored AWS provider to resolve and hydrate v2 credentials asynchronously before building v3 client config. Updated related methods to be async and added logic to handle lazy credential providers, improving compatibility with various AWS credential sources.

Summary
SLS_AWS_SDK_V3=1was failing${ssm:...}resolution withUnrecognizedClientExceptionbecause Serverless forced early resolution of AWS SDK v2 credentials and copied them into SDK v3. Since credentials sourced from environment variables were not valid at that point in execution, the resolved credentials were incorrect and then reused by SDK v3.await getPromise/refreshPromise(when present) in_resolveV2CredentialsForV3, so the v3 client config receives realaccessKeyId,secretAccessKeyandsessionToken. If no keys are available, we return undefined and allow SDK v3 to fall back to its own credential provider chain
