Add ChatClient Support to ChatCompletionAgent

Resolve .Net: Support M.E.AI Abstractions - Enable Agents to use IChatClient's natively from Kernel and DI. #10729

Motivation and Context

This PR enhances ChatCompletionAgent to support IChatClient alongside existing IChatCompletionService, providing more flexibility in how chat completions are handled. This enables better integration with existing Microsoft.Extensions.AI types.

Description

Core Changes

Enhanced ChatCompletionAgent to:
- Support both IChatClient and IChatCompletionService interfaces
- Maintain backward compatibility with existing implementations
Updated Sample Code:
- Added new examples in Concepts demonstrating ChatClient usage
- Updated Getting Started With Agents samples to showcase both service types
Added Comprehensive Unit Tests:
- Test coverage for Agents with ChatClient integration
- Verification of both streaming and non-streaming scenarios
Added IChatClient.AsKernelFunctionInvokingClient extension method to enable Kernel Function Invocation support with IChatClient for solutions that target .NET 8 LTS only.
