Details:
Aligned with the canonical form of the dequantization subgraph.
Reshape op has been moved up right after the Constant, it will be const folded in MOC, this is ok, Reshape const folding doesn't copy a constant, just copies a pointer.
And ConvertLike were replaced with Convert. Perhaps that's a pretty rough change and we need to add a check here that the scale is a contant. And in that case use Convert instead of ConvertLike, if scale is not a constant, maybe we should leave ConvertLike.
