Fix T62282: multires sculpting does not update smooth normals
It may be good to move the normals update out of the drawing code. But it was
already there for the non-multires sculpt cases, and does not have an obvious
place since we bypass the depsgraph and want to avoid the cost of updating the
normals multiple times when multiple events are handled before a redraw.
