Add Vision Model Upload Functionality and Enhance Training Workflow

- Introduced new upload_vision.py script for comprehensive model upload capabilities
- Extended train_vision.py with additional upload methods for Hugging Face and Ollama
- Added support for saving merged models, pushing GGUF models, and creating Ollama models
- Implemented flexible upload targeting with configurable options
- Enhanced model preparation and deployment workflow for vision models
