5b3e316039 d3d11: Port to C++ 
Direct3D11 objects are COM, and most COM C APIs are verbose
(C++ is a little better). So, by using C++ APIs, we can make code
shorter and more readable.
Moreover, "ComPtr" helper class (which is C++ only) can be
utilized, that is very helpful for avoiding error-prone COM refcounting
issue/leak.

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.

ac04681b6f d3d11device: Remove optional helper methods 
Most of Direct3D11 APIs can be called without GstD3D11Device
abstraction. This is a part of prework for public GstD3D11 library
to introduce minimal APIs
