d3d11: Implement fence abstraction
Depending on device feature level, d3d11 runtime can support ID3D11Fence which is equivalent to ID3D12Fence. Waiting using fence has performance-wise benefit over pulling ID3D11Query status. If ID3D11Fence is not supported by device, then ID3D11Query will be used instead. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2790>
