Are we going to have separate error codes for each missing feature? Or could we e.g. have VKD3D_SHADER_ERROR_SPV_UNSUPPORTED_FEATURE? I suppose we have precedent in VKD3D_SHADER_ERROR_SPV_DESCRIPTOR_IDX_UNSUPPORTED and VKD3D_SHADER_ERROR_SPV_STENCIL_EXPORT_UNSUPPORTED, but in theory we could e.g. decide to rename VKD3D_SHADER_ERROR_SPV_STENCIL_EXPORT_UNSUPPORTED to VKD3D_SHADER_ERROR_SPV_UNSUPPORTED_FEATURE and then use that going forward.

This is not the first test to use doubles, but the preceding commit makes the issue here perhaps more obvious: doubles aren't universally supported. Direct3D 12 has D3D12_FEATURE_DATA_D3D12_OPTIONS.DoublePrecisionFloatShaderOps, Direct3D 11 has D3D11_FEATURE_DATA_DOUBLES.DoublePrecisionFloatShaderOps, Vulkan has VkPhysicalDeviceFeatures.shaderFloat64, and OpenGL has GL_ARB_gpu_shader_fp64.
