Added SDL_GetTextureDXGIResource() to get the DXGI resource associated with a render texture.

Also switched the D3D11 and D3D12 renderers to use real NV12 textures for NV12 data.

The combination of these two changes allows us to implement 0-copy video decode and playback for D3D11 in testffmpeg without any access to the renderer internals.
