fix: standardize provider interface parameters across all implementations

- Add screen_size parameter to get_vm_path() for all providers (with default 1920x1080)
- Add os_type parameter to start_emulator() for Azure and VirtualBox providers
- Add region parameter to stop_emulator() for VMware, Docker, and VirtualBox providers
- Use *args, **kwargs for better extensibility and parameter consistency
- Add documentation comments explaining ignored parameters for interface consistency
- Prevents TypeError exceptions when AWS-specific parameters are passed to other providers

This ensures all providers can handle the same parameter sets while maintaining
backward compatibility and avoiding interface fragmentation.
