2ca298d459 d3d11: Re-implement Desktop Duplication source
Add a new video source element "d3d11desktopdupsrc" for capturing desktop image
via Desktop Duplication based on Microsoft's Desktop Duplication sample available at
https://github.com/microsoft/Windows-classic-samples/tree/master/Samples/DXGIDesktopDuplication

This element is expected to be a replacement of existing dxgiscreencapsrc
element in winscreencap plugin.

Currently this element can support (but dxgiscreencapsrc cannot)
- Copying captured D3D11 texture to output buffer without download
- Support desktop session transition
  e.g., can capture desktop without error even in case that
  "Lock desktop" and "Permission dialog"
- Multiple d3d11desktopdupsrc elements can capture the same monitor

Not yet implemented features
- Cropping rect is not implemented, but that can be handled by downstream
- Mult-monitor is not supported. But that is also can be implemented by
  downstream element for example via multiple d3d11desktopdup elements
  with d3d11compositor

96831233a3 d3d11videosink: Add a property to support rendering statistics data on window
Add a new property "render-stats" to allow rendering statistics
data on window for debugging and/or development purpose.
Text rendering will be accelerated by GPU since this implementation
uses Direct2D/DirectWrite API and Direct3D inter-op for minimal overhead.
Specifically, text data will be rendered on swapchain backbuffer
directly without any copy/allocation of extra texture.

6e30cbb3fc d3d11: Introduce d3d11compositor element
Add new video composition element which is equivalent to compositor
and glvideomixer elements. When d3d11 decoder elements are used,
d3d11compositor can do efficient graphics memory handling
(zero copying or at least copying memory on GPU memory space).

387b6df948 meson: Don't use get_option('buildtype')
We should directly check the values of the `debug` and `optimization`
options instead.

`get_option('buildtype')` will return `'custom'` for most combinations
of `-Doptimization` and `-Ddebug`, but those two will always be set
correctly if only `-Dbuildtype` is set. So we should look at those
options directly.

For the two-way mapping between `buildtype` and `optimization`
+ `debug`, see this table:

00d04784d3 Move CODEC base classes into it's own library
This introduce a library which contains a set of base classes which
handles the parsing and the state tracking for the purpose of decoding
different CODECs. Currently H264, H265 and VP9 are supported. These
bases classes are used to decode with low level decoding API like DXVA,
NVDEC, VDPAU, VAAPI and V4L2 State Less decoders. The new library is
named gstreamer-codecs-1.0 / libgstcodecs.

6c3311a39e d3d11: Refactor d3d11 memory and dxgi format usage
* Create staging texture only when the CPU access is requested.
Note that we should avoid the CPU access to d3d11 memory as mush as possible.
Incoming d3d11upload and d3d11download will take this GPU memory upload/download.

* Upload/Download texture memory from/to staging only if it needed, similar to
GstGL PBO implementation.

* Define more dxgi formats for future usage (e.g., color conversion, dxva2 decoder).
Because I420_* formats are not supported formats by dxgi, each plane should
be handled likewise GstGL separately, but NV12/P10 formats might be supported ones.
So we decide the number of d3d11memory per GstBuffer for video memory depending on
OS version and dxgi format. For instance, if NV12 is supported by OS,
only one d3d11memory with DXGI_FORMAT_NV12 texture can be allocated by this commit.
One use case of such texture is DXVA. In case DXVA decoder, it might need to produce decoded data
to one DXGI_FORMAT_NV12 instead of seperate Y and UV planes.
Such behavior will be controlled via configuration of GstD3D11BufferPool and
default configuration is separate resources per plane.

5c3879ace6 d3d11videosink: Add new Direct3D11 video render plugin
Direct3D11 was shipped as part of Windows7 and it's obviously
primary graphics API on Windows.

This plugin includes HDR10 rendering if following requirements are satisfied
* IDXGISwapChain4::SetHDRMetaData is available (decleared in dxgi1_5.h)
* Display can support DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020 color space
