12baab442c d3d11memory: Add a method for querying texture array size 
... and the number of textures in use.

Direct3D11 texture array is usually used for decoder DPB pool,
and d3d11 decoder elements might want to know
whether there's available texture resource or not.

0b0bf1b0bf d3d11: Suppress some warning debug messages 
* Don't warn for live object, since ID3D11Debug itself seems to be
  holding refcount of ID3D11Device at the moment we called
  ID3D11Debug::ReportLiveDeviceObjects(). It would report live object
  always
* Device might not be able to support some formats (e.g., P010)
  especially in case of WARP device. We don't need to warn about that.
* gst_d3d11_device_new() can be used for device enumeration. Don't warn
  even if we cannot create D3D11 device with given adapter index therefore.
* Don't warn for HLSL compiler warning. It's just noise and
  should not be critical thing at all

d16b5b7f7f d3d11: Allow building UWP features with Desktop features if possible 
WINAPI_PARTITION_DESKTOP and WINAPI_PARTITION_APP can coexist.
Although UWP only binaries should be used for production stage,
this change will be useful for development stage

0f7af4b143 d3d11: Move core methods to gst-libs 
Move d3d11 device, memory, buffer pool and minimal method
to gst-libs so that other plugins can access d3d11 resource.
Since Direct3D is primary graphics API on Windows, we need
this infrastructure for various plugins can share GPU resource
without downloading GPU memory.
Note that this implementation is public only for -bad scope
for now.
