Seungha Yang 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

/**
* SECTION:plugin-d3d11
*
* Microsoft Direct3D11 plugin.
*
* This plugin consists of various video filter, screen capture source,
* video sink, and video decoder elements.
*
* GstD3D11 plugin supports H.264/AVC, H.265/HEVC, VP8, VP9, H.262/MPEG-2 video,
* and AV1 codecs for decoding as well as hardware-accelerated video
* deinterlacing. Note that minimum required OS version for video decoder and
* deinterlacing elements is Windows 8.
*
* Plugin feature names of decoders:
* - d3d11h264dec
* - d3d11h265dec
* - d3d11vp8dec
* - d3d11vp9dec
* - d3d11mpeg2dec
* - d3d11av1dec
*
* Similar to the video decoder case, deinterlacing element would be registered
* only if its supported by hardware with the feature name `d3d11deinterlace`
*
* However, depending on the hardware it runs on, some elements might not be
* registered in case that underlying hardware doesn't support the feature.
* For a system with multiple Direct3D11 compatible hardwares (i.e., GPU),
* there can be multiple plugin features having the same role.
* The naming rule for the non-primary decoder element is
* `d3d11{codec}device{index}dec` where `index` is an arbitrary index number of
* hardware starting from 1.
*
* To get a list of all available elements, user can run
* ```sh
* gst-inspect-1.0.exe d3d11
* ```
*
