In VulkanConfigureation.h remove FENCE Code if possible.

Custom build

/Engine/Source/Runtime/VulkanRHI/Public/VulkanConfiguration.h

```cpp
- #define VULKAN_USE_IMAGE_ACQUIRE_FENCES 1
+ #define VULKAN_USE_IMAGE_ACQUIRE_FENCES 0

```

The engine is suddenly completely stable on linux and running the most amazing I have ever seen it. If it’s not truly needed. Get it it out of there.. ASAP

The vulkan issues are completely gone and I swear my fps has tripled.
