wined3d: Use the format info to calculate compressed surface pitch in IWineD3DBaseSurfaceImpl_GetPitch().

wined3d: Use the format info to calculate compressed surface size in IWineD3DBaseSurfaceImpl_SetFormat().

wined3d: Use the format info to calculate compressed surface size in IWineD3DDeviceImpl_CreateSurface().

If the extension isn't available to surface shouldn't have been created. We
don't do extension checks for all the other formats either.
