D3D11: Use system memory for dynamic buffer updates. In our current code, we would use a staging texture as the working copy for buffer updates. This would trigger very large memcpy calls in some cases for large buffers with small updates. Instead, use a CPU memory buffer storage, and work with this storage when the user updates data. This plays much nicer with the VertexDataManager.
