Enhance MIG Support Detection for NVIDIA GPUs introduced in R580

[RuixiangMa]

Summary

This PR significantly improves the Multi-Instance GPU (MIG) capability detection logic in the NVIDIA GPU Operator by expanding the list of supported GPU architectures and implementing a more comprehensive pattern-matching approach.

Changes Made

1. Enhanced MIG Detection Logic (controllers/state_manager.go)

• Refactored the hasMIGCapableGPU function to use a dedicated helper function isMIGCapableGPUProduct
• Expanded MIG support from 3 basic models to comprehensive architecture coverage
• Implemented structured pattern matching with clear architectural categorization

2. Comprehensive GPU Architecture Support

The updated detection now supports:

Hopper Architecture (Data Center)

• H100, H800, H200, H20，GH200

Ampere Architecture

• A100, A800, A30

Blackwell Architecture (Next Generation)

• GB200, B200, GB300, B300

Professional Workstation GPUs

• RTX PRO 6000
• RTX PRO 5000
• Dual format support: Both "rtx-pro-6000" and "rtx pro 6000" naming conventions

Verification and Testing

Test Coverage

• All supported GPU models across architectures
• Multiple naming format variations
• Negative test cases for non-MIG GPUs (T4, V100)
• Edge cases (empty strings, partial matches)
