bugfix [#19254] KX_PolyProxy returns improper VertexIndex with triangles, using .getVertexIndex() and .v1, .v2, etc.
Surprising this wasn't noticed before. Any mix of quads/tris caused the face verts of either quads/tries (whichever comes last).
Tested by exporting the KX_MeshProxy and re-importing as an OBJ.
This fix assumes there are only 2 m_darray's per face array which is currently true, but wont be if edge support is added back.
