wined3d: Introduce WINED3D_LOCATION_CLEARED and use it for the initial state of buffers.
The practical effect of this is to defer clearing buffers until they are used. Under normal circumstances the buffer will be initially discarded, in which case we need not clear it at all, and may even avoid ever allocating sysmem.
