Goal

Extend the existing RuntimeClass management logic (KATA-3968) to support GPU-CC workloads.

Why this matters

Extending the logic to create the appropriate runtimeclass and its corresponding handler for GPU-CC 

Acceptance Criteria

The story will be complete when the following logic is included:

• create RuntimeClass for kata-cc-gpu (or kata-nvidia-gpu-cc)
• Set handler to kata-cc-gpu-intel (TDX) or kata-cc-gpu-amd (SNP)
• Clean up kata-cc-gpu RuntimeClass when GPU-CC feature is disabled
