Fix T84376: Skin Resize(Ctrl + A) does not work in Symmetry

Since the `TransData` converted from vertices is the same used for other
transform modes (Move, Rotate, Resize), the logic used for mirroring
focused only on the position of the vertices.

The solution here is to create a specific `TansData` for `CD_MVERT_SKIN`.
