BGE: Fix T38030: wrong vertex index returned by KX_PolyProxy

Fix T38030.
In c++ source we use one list for triangles and an other for quads, but KX_PolyProxy doesn't care about that and return the vertex offset in its list. So we just have to compute the offset of each RAS_DisplayArray to its previous to have an absolute vertex index.
