feat: add High-End and Insane VRAM modes with leak prevention

- Add HighEnd and Insane VRAM usage modes for RTX 4090/4080+ users
- Implement VRAM limits: HighEnd (12GB), Insane (22GB) with scaling
- Optimize buffer allocation with larger chunks for high-end GPUs
- Add VRAM leak detection and aggressive cleanup for Insane mode
- Increase shader compilation buffer sizes for better performance
- Add VRAM monitoring functions to Vulkan rasterizer
- Implement memory usage tracking for staging buffers
