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.

32eeadb4a5 d3d11: Define enum and flags types manually
gnome.mkenums_simple() doesn't work well for GstD3D11, seems to
be confused by numeric representation of D3D11, must be a bug
in GLib or so. Just don't rely on the incomplete automagic.

1dd29a2564 d3d11: Move HLSL compiler to gst-libs
We should move this functionality to gst-libs so that GstD3D11Converter
can be moved to gst-libs.
Another advantage is that applications can call our
HLSL compiler wrapper method without any worry about OS version
dependent system installed HLSL library.
Note that there are multiple HLSL compiler library versions
on Windows and system installed one would be OS version dependent.

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.

170271b86f d3d11: Revert staging buffer pool implementation
The staging buffer pool implementation was added to improve
throughput performance since we can avoid per-frame
CPU copy operation via staging texture but it turned out that
we can not make it thread safe. See
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1182

Reverting the staging texture implementation as it does not show
any visible value.

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.
