st/mesa: treat 1D ARRAY upload like a depth or 2D array upload.
This is because the HW doesn't always store a 1D array like a 2D texture, it more likely stores it like 2D texture (i.e. alignments etc). This means we upload each slice separately and let the driver work out where to put it. this might break nvc0 as I can't test it, I have only nv50 here.
