feat: add Intel Arc and Arc Pro GPU support

[inureyes]

Description

Add support for Intel Arc and Arc Pro GPUs to the all-smi library. Intel Arc is Intel's discrete GPU lineup based on the Xe HPG (High Performance Gaming) architecture, featuring XMX (Xe Matrix Extensions) engines for AI/ML acceleration.

GPU Series Overview

Intel Arc (Consumer)

• Arc A770, A750, A580, A380, A310
• Targeted at gaming and content creation
• Features ray tracing and XeSS (Xe Super Sampling) AI upscaling

Intel Arc Pro (Professional/Workstation)

• Arc Pro A60, A50, A40, A30M
• Optimized for professional workflows
• Certified drivers for professional applications

Key Implementation Requirements

Core Features

• Detection: Implement detection capabilities for both Intel Arc and Arc Pro GPUs
• Driver Version: Extract and expose Intel Graphics Driver version information
• Monitoring: Implement real-time monitoring capabilities for:
  • GPU utilization (render, compute, media engines)
  • Memory usage (dedicated VRAM and shared memory)
  • Temperature monitoring
  • Power consumption
  • XMX engine utilization for AI workloads

Implementation Guidelines

• Follow the existing architectural pattern used for other GPUs (AMD, NVIDIA)
• Implement caching for static values (similar to the optimization in perf: optimize GPU/NPU readers by caching static values #69)
• Use the unified AI acceleration library naming conventions introduced in feat: add unified AI acceleration library naming for cross-platform consistency #67
• Ensure cross-platform compatibility (Linux and Windows)

Mock Server Support

• Add mock endpoints for Intel Arc GPU metrics in the mock server
• Include realistic sample data for testing and development
• Follow the existing mock server patterns for AMD and NVIDIA implementations

API Endpoints

• Extend the existing API to include Intel Arc GPU specific endpoints
• Ensure consistent response format with other GPU types
• Include all relevant metrics in the API responses

Technical Considerations

Primary Tools

• xpu-smi: Intel's XPU System Management Interface tool (preferred)
• intel_gpu_top: Real-time GPU monitoring utility (Linux fallback)

Driver Stack

• Linux: i915 or xe driver with Level Zero runtime
• Windows: Intel Graphics Driver with Level Zero runtime

Key Differences from Intel Gaudi

Aspect	Intel Arc	Intel Gaudi
Purpose	General-purpose GPU (graphics + compute + AI)	Dedicated AI accelerator
Tool	xpu-smi, intel_gpu_top	hl-smi
Driver	i915/xe	habanalabs
API	Level Zero, oneAPI	Habana SynapseAI

Cross-Platform Support

• Level Zero API provides unified access across platforms
• Consider oneAPI toolkit integration for advanced features

Testing Requirements

• Unit tests for all new Intel Arc detection and monitoring functions
• Integration tests with the mock server
• Test coverage for both Arc (consumer) and Arc Pro (professional) variants
• Documentation updates for the new Intel Arc support
