new feature: support AWS SSO Credentials Provider

### Feature Description

Like in official AWS Rust SDK: https://docs.rs/aws-config/latest/aws_config/sso/credentials/struct.SsoCredentialsProvider.html, it's usually used in corporate environment.

### Problem and Solution

AWS SSO config in `~/.aws/config` should work out of the box when using opendal to access S3.

### Additional Context

_No response_

### Are you willing to contribute to the development of this feature?

- [ ] Yes, I am willing to contribute to the development of this feature.

Start with the official AWS Rust SDK SsoCredentialsProvider documentation and inspect how OpenDAL loads credentials for S3 from ~/.aws/config. Determine the integration entry point and required behavior for AWS SSO profiles; it is done when an SSO-configured profile works out of the box for S3 access.
