Fixing below debug layer report ID3D12Device::CreateCommittedResource: Ignoring InitialState D3D12_RESOURCE_STATE_COPY_DEST. Buffers are effectively created in state D3D12_RESOURCE_STATE_COMMON. Buffer resource will be automatically promoted to D3D12_RESOURCE_STATE_COPY_DEST at the very first COPY operation time.
