feat(vulkan): improve error handling for Vulkan queue submission

- Added handling for VK_ERROR_DEVICE_LOST during queue submission to prevent application termination.
- Enhanced logging to provide clearer diagnostics for GPU driver issues and potential rendering artifacts.
- Maintained standard error handling for other Vulkan submission errors to ensure robust operation.
