Azure AI Foundry Integration for Microsoft Agent Framework

The `agent-framework-azure-ai` library provides an integration layer for various Azure AI services (e.g., Azure OpenAI, Azure AI Search, Azure Speech, Azure Vision) with the Microsoft Agent Framework. It enables developers to easily incorporate these powerful Azure capabilities into their agent-based applications. Currently at version `1.0.0rc6`, its release cadence is tied to the evolving Microsoft Agent Framework and Azure AI services, with new release candidates emerging as features stabilize.
