Observed Intel GPU driver crash when multiple decoders are
configured in a process. It might be because of frequent

Adding new property in order to notify users of device removed status.
Once device removed status is detected, application should release
all ID3D12Device objects corresponding to the adapter, including
GstD3D12Device object. Otherwise D3D12CreateDevice() call for the
adapter will fail.
