net/mlx5e: Rearrange tc tunnel code in a modular way
Rearrange tc tunnel code so that it would be easy to add future tunnels:
- Define tc tunnel object with the fields and callbacks that any
tunnel must implement.
- Define tc UDP tunnel object for UDP tunnels, such as VXLAN
- Move each tunnel code (GRE, VXLAN) to its own separate file
- Rewrite tc tunnel implementation in a general way - using only
the objects and their callbacks.
