Add ARM64 Docker build and deployment support for Raspberry Pi and Jetson Nano

[HuYingTran]

• Introduce support for building and deploying the XiaoZhi server on ARM64 platforms such as Raspberry Pi 4 (8GB or higher) and NVIDIA Jetson Nano using Docker.
• Utilize Docker Buildx to create multi-architecture images optimized for ARM64.
• Update docker-setup-arm.sh, Dockerfiles-server-arm and docker-compose_arm.yml configurations to ensure compatibility with ARM64 environments.
• Automate installation of required components (Docker, buildx) and streamline server configuration through setup scripts.
• Simplify deployment: instead of manually building Docker images, users now only need to run a single command:
  sudo bash docker-setup-arm.sh
  which handles all installation, image building, and container startup automatically.
