824b0ce0f4 Revert "d3d11: Enable native multi-thread protection layer and make use of it" 
This reverts commit 872b7f503c.

Native multi-thread protection layer seems to be consuming more CPU
resource than application side protection approach in some cases

872b7f503c d3d11: Enable native multi-thread protection layer and make use of it 
... instead of our own GRecMutex locking. In this way, any other
Direct3D11 client (MediaFoundation for example) can safely call
any Direct3D11 API even when we are sharing our Direct3D11 device
with others.

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.

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.
