d3d11device: Add fallback for device creation

Browse source 
D3D11_CREATE_DEVICE_DEBUG flag will be used while creating d3d11 device
to activate debug layer. However, if system doesn't support the
debug layer for some reason, we should try to create d3d11 device
without the flag. Debug layer should be optional for device creation.
