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.

1c3fac818d d3d11: Move GstD3D11Converter to gst-libs
The object is equivalent to GstVideoConverter but for D3D11.
Application can use this object directly for various conversions,
such as color space conversion, rescale, crop and flip/rotation.

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.

e96687d88d d3d11: Update build-time dependency
Remove all the d3d11 and dxgi header version dependent ifdef
and bump the minimum requirement to d3d11_4.h and dxgi1_6.h.
We are already failing support old Visual Studio (Windows SDK actually)
such as Visual Studio 2015. Note that our MinGW toolchain satisfies
the requirement.

From runtime point of view, this change should be fine since
we are checking OS version with IUnknown::QueryInterface()
everywhere in order to check API availability

06fb2d3937 d3d11: Add new buffer pool implementation for staging texture
staging buffer pool will allocate staging d3d11 texture
for upload/download optimization. By using staging buffer,
we can avoid per frame staging -> system memory copy operation.
