refactor: Enhance service architecture by introducing IPlatformService and updating dependencies

- Removed core/platform.hpp and core/vulkan_utils.cpp, integrating their functionality into new platform_service implementations.
- Updated service registrations to utilize IPlatformService for improved modularity.
- Refactored event bus usage across services to leverage IEventBus interface.
- Enhanced buffer management in BufferService with detailed logging and error handling.
- Updated GUI rendering services to utilize buffer service for resource management.
- Cleaned up includes and improved overall code organization for better maintainability.
