Jörg Thalheim 3034589047 libstore: add AWS SSO support for S3 authentication
This enables seamless AWS SSO authentication for S3 binary caches
without requiring users to manually export credentials.

This adds SSO support by calling aws_credentials_provider_new_sso() from
the C library directly. It builds a custom credential chain: Env → SSO →
Profile → IMDS

The SSO provider requires a TLS context for HTTPS connections to SSO
endpoints, which is created once and shared across all providers.
