Fix Vulkan Android implementation and RAII migration issues
- Addressed Vulkan RAII object handling with proper dereferencing using `*`. - Adjusted Vulkan profile compatibility for Android and non-Android platforms. - Updated API version to `VK_API_VERSION_1_3` and removed unused extensions. - Simplified debug messenger setup for code compatibility. - Updated Android lifecycle handling to improve Vulkan initialization. - Fixed transition from `ALooper_pollAll` to `ALooper_pollOnce` in event handling.
