Only reupload the texture scale array if it changes. (#2595)
* Only reupload the texture scale array if it changes. Before, this would be called all the time if any shader needed a scale value. The cost of doing this has increased with threaded-gal, as the scale array is copied to a span pool, and it's was called on pretty much every draw sometimes. This improves GPU performance in games, scaled or not. Most affected game seems to be Xenoblade Chronicles: Definitive Edition. * Just use = instead of |=
