PR Overview

This pull request adds support for additional Azure AI Agent tool types – including Function, File Search, Code Interpreter, Bing Grounding, and Open API – while updating the YAML converters and sample definitions accordingly.

• Updated the agent tool extension methods to improve handling of tool configurations and parameters.
• Modified sample agent definitions to use the new "foundry_agent" type and added new test cases for each tool type.
• Revised YAML converters and the agent factory to incorporate the new resources and configuration checks.
