[pvaneck]

Closes: #42045

Pull Request Overview

This PR fixes an issue where CAE (Continuous Access Evaluation) caches were not properly used by AuthorizationCodeCredential and the asynchronous OnBehalfOfCredential when accessing refresh tokens. The fix ensures that the appropriate cache (CAE or regular) is used based on the enable_cae parameter when retrieving cached refresh tokens.

Key changes:

• Updated both credential classes to pass through kwargs when calling get_cached_refresh_tokens() to respect CAE settings
• Enhanced test coverage to verify CAE functionality works correctly for both credential types
• Added proper cache selection logic in tests to validate the correct cache is being used

• [nitpick] The variable name 'cache_being_used' could be more descriptive. Consider renaming it to 'target_cache' or 'selected_cache' to better convey its purpose.

    cache_being_used = cae_cache if enable_cae else cache
