net/mlx5e: Move tc tunnel parsing logic with the rest at tc_tun module
Currently, tunnel parsing is split between en_tc and tc_tun. The next
patch will replace the tunnel fields matching with a register match,
and will not need this parsing.
Move the tunnel parsing logic to tc_tun as a pre-step for skipping
it in the next patch.
