Enable HW acceleration on Windows with D3D11 textures
This patch enables HW accelerated decoding of video with D3D11.
The decoded frames arrive as a texture array with an index into
the array pointing to where the decoded frame is located. This texture
is shared with the D3D11 display device.
Two elements are missing:
1) D3D11 rendered texture sharing with OpenGL display QRhi
2) Seting up the correct D3D11 adapter for texture decoding to
avoid copying texture between decoding adapter and displaying adapter
