Change these

Since some drivers have Mesh Shader support without support in pipeline statistics, it is important to use CheckFeatureSupport to query D3D12_FEATURE_DATA_D3D12_OPTIONS8 for MeshShaderPipelineStatsSupported before using Pipeline Statistics to evaluate mesh shader or amplification shader data.

D3D12_FEATURE_DATA_D3D12_OPTIONS8 featureData = {};
pDevice->CheckFeatureSupport(D3D12_FEATURE_D3D12_OPTIONS8, &featureData, sizeof(featureData));
VERIFY_IS_TRUE(featureData.MeshShaderPipelineStatsSupported);
