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.

aca71fd692 d3d11: Update gst_d3d11_allocation_params_new() interface
Define GST_D3D11_ALLOCATION_FLAG_DEFAULT (0) value instead of
casting enum type everywhere. And pass D3D11_RESOURCE_MISC_FLAG value

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.

e0a9a73adf d3d11screencapturesrc: Fix crash when d3d11 device is different from owned one
GstD3D11ScreenCapture object is pipeline-independent global object
and the object can be shared by multiple src elements,
in order to overcome a limitation of DXGI Desktop Duplication API.
Note that the API allows only single capture session in a process for
a monitor.

Therefore GstD3D11ScreenCapture object must be able to handle a case
where a src element holds different GstD3D11Device object. Which can
happen when GstD3D11Device context is not shared by pipelines.

What's changed:
* Allocates capture texture with D3D11_RESOURCE_MISC_SHARED for the
  texture to be able to copied into other device's texture
* Holds additional shader objects per src element and use it when drawing
  mouse
