New failing test family for CTS 1.0 dEQP-VK.image.atomic_operations.*.cube*

[aitor-lunarg]

I just did a new run on CTS 1.0 and found out that there mentioned test family dEQP-VK.image.atomic_operations.*.cube* is now failing. Testing with 872d13d and vulkan-cts-1.3.8 ToT (6129a7e275ed24851aab2357c13761d034cc4212).

Creating the issue as a tracker. I have yet to triage to understand where the issue may come from, but I don't believe they are new tests. @billhollings any changes that may have happened around atomic operations on cube textures?

So, the reason why these tests fail is because Metal does not support atomic operations for cube textures. In MoltenVK we report that the format supports atomic operations since that's the Vulkan way to let applications know about that features.

Due to this mismatch in how Vulkan allows to report such feature, the way forward would be to lower the cube texture to a 2D array texture to allow for atomic operations (Metal allows atomic operations for 2D array textures but not for cube textures).
