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

By using staging pool/buffer, we can avoid per frame
staging texture -> system memory copy.
