    net/mlx5e: Extract tc tunnel encap/decap code to dedicated file
    
    Following patches in series extend the extracted code with routing
    infrastructure. To improve code modularity created a dedicated
    tc_tun_encap.c source file and move encap/decap related code to the new
    file. Export code that is used by both regular TC code and encap/decap code
    into tc_priv.h (new header intended to be used only by TC module). Rename
    some exported functions by adding "mlx5e_" prefix to their names.

Note: switching on NET_SWITCHDEV fixes the build error.
