Subject: [PATCH] chore: Clarify support-related Exceptions in utils.py (#5447)

Improved the clarity of Exceptions in supports_system_messages, supports_response_schema, supports_function_calling, and supports_parallel_function_calling. Previously, it was difficult to determine the cause of Exception logs due to vague messaging. Each case now includes a more specific and appropriate Exception message.
