dEQP-VK.subgroups.quad.graphics ignores quadOperationsInAllStages property

[jenatali]

I'm enabling subgroup quad ops in Dozen/VkOn12, and D3D12 only supports quad ops in pixel/fragment shaders and compute shaders (and other compute-like shaders, i.e. mesh), so I'm setting quadOperationsInAllStages to false. But I see the CTS attempting to use quad ops in a vertex shader.

Searching for the symbol, I don't see any hits in the subgroup tests at all. That seems like a mistake.
