feat(vulkan): implement enhanced texture and shader management

This commit adds improved Vulkan functionality to the Citron emulator:

- Add thread-safe texture management with automatic error recovery
- Implement shader caching with validation support
- Add robust error handling for Vulkan operations
- Implement platform-specific initialization for Windows, Linux, and Android

These enhancements improve stability when handling texture loading errors
and provide better recovery mechanisms for Vulkan failures.
