ba259111d5 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.

fce7431381 d3d11: Install library headers
Our Direct3D11 abstraction layer has been improved and
it gained good shape from API point of view.
Also, On Windows, GstD3D11 has various advantages over GstGL
in terms of compatibility/stability/feature/performance.
Note that WGL implementation is known to be buggy for some
drivers/vendors/scenario (that's a reason why Google implemented ANGLE).
Moreover, GstGL is not fully optimized for Windows unfortunately.

It's the time to open this interface to application developers
for various optimized processing using our Direct3D11
infrastructure.

dd906f9610 d3d11: Store device format in struct
Holding pointer to struct was unsafe approach because
the pointer to d3d11 format will be invalidated once d3d11 device
object is released

5ac7a21ef0 d3d11: d3d11device: Add gst_d3d11_device_new_{for_adapter_luid,wrapped}
* gst_d3d11_device_new_for_adapter_luid()
  Used for creating D3D11 device for a DXGI adapter (i.e., GPU)
  corresponding to a LUID (Locally Unique Identifier).
  This method can be useful for interop with other APIs such as
  Direct3D12, MediaFoundation, CUDA, etc.
* gst_d3d11_device_new_wrapped()
  Allows creating a new GstD3D11Device object by using already
  configured ID3D11Device. This is conceptually equivalent to
  gst_gl_context_new_wrapped()
