[Board] Add support for my board of XiaozhiAI

[Jessefan1988]

Description

This PR adds the board configuration files for a custom ESP32-S3 board, located in the application/edge_agent/boards/XiaozhiAI directory. The configuration includes board_info.yaml, board_peripherals.yaml, and board_devices.yaml.

This board is a custom design based on the ESP32-S3, intended for comprehensive AIoT and edge AI applications. It features a rich set of peripherals to support multi-modal AI applications (vision, audio, and display). This contribution aims to make the board fully compatible with the ESP-Claw framework, allowing for easy development and deployment.
