GPencil: Fix unreported error baking mesh animation

When the mesh is linked, the materials can not be available or be the same assigned to mesh. Now, if the mesh is linked, a simple two materials conversion is used.

To get the full list of materials, the mesh must not be linked.

Also checked some indexes to be sure never get a wrong value and that materials are not created again and again.
