cf94045dbf qsvencoder: Add support for D3D11 shared texture
Although input texture belongs to the other d3d11 device,
we can do GPU copy when its physical device is identical.

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.

44768b233a qsvencoder: Do not copy if input is D3D11 texture
In case that input is D3D11 texture, QSV seems to work regardless
of the alignment. Actually the alignment requirement seems to make
only sense for system memory.
Other Intel GPU dependent implementations (new VA encoder, and MediaFoundation)
do not require such alignment nor other vendor specific ones (NVENC and AMF)

Note that YUY2 is not supported yet, since the format support is not
implemented now.

64ed6075b7 qsv: Introduce H.264 Intel Quick Sync Video Encoder
A new implementation of Intel Quick Sync Video plugin.
This plugin supports both Windows and Linux but optimization for
VA/DMABuf is not implemented yet.

This new plugin has some notable differences compared with existing
MSDK plugin.

* Encoder will expose formats which can be natively supported
without internal conversion. This will make encoder
control/negotiation flow much simpler and cleaner than
that of MSDK plugin.

* This plugin includes QSV specific library loading helper,
called dispatcher, with QSV SDK headers as a part of this plugin.
So, there will be no more SDK version dependent #ifdef in the code
and also there will be no more build-time MSDK/oneVPL SDK
dependency.

* Memory allocator interop between GStreamer and QSV is re-designed
and decoupled. Instead of implementing QSV specific allocator/bufferpool,
this plugin will make use of generic GStreamer memory
allocator/bufferpool (e.g., GstD3D11Allocator and GstD3D11BufferPool).
Specifically, GstQsvAllocator object will help interop between
GstMemory and mfxFrameAllocator memory abstraction layers.

Note that because of the design decision, VA/DMABuf support is not made
as a part of this initial commit. We can add the optimization for Linux
later once GstVA library exposes allocator/bufferpool implementation as
an API like GstD3D11.

* Initial encoder implementation supports interop with GstD3D11
infrastructure, including zero-copy encoding with upstream D3D11 element.
