MLBEDSW-11114 Transpose H/W if H is dominating on non-const Convs
The height of decomposed convs with non-constant weights is always 1. To improve the performance of tall such ops, this change adds a heuristic to swap height and width as well as kernel parameters if height is significantly larger than width.
