Initialize buffer contents separately from BufferImpl::setData Some backends can initialize buffer data faster than allocating a zero-filled scratch buffer (GL can map and memset for example). Allow those backends the opportunity to make these optimizations. Verified that GL, D3D and VK backends do not regress by using a separate set data call.
