Right now, Vulkan ignores the specified WaveSize attribute in the HLSL.
In the device creation code, there is no mention of VK_EXT_subgroup_size_control to set the wave size based on the attribute in the HLSL.
So, when Vulkan is the IR target, the device will just use the default wave size.
This issue tracks updating the test infrastructure so that the wave size specified in the HLSL is properly referenced, or an error is raised if the device doesn't support it.
We have various tests that rely on the WaveSize attribute to control the wave size ("subgroup size" in Vulkan terms). Vulkan/SPIRV doesn't have an equivalent to this attribute, but instead has the VK_EXT_subgroup_size_control extension that can be used for the same purpose.
For this task we should:
- find a way to expose this via the pipeline yaml
- expose supported subgroup sizes that can be used in REQUIRES clauses.
- update the existing tests to use it
