net/mlx5: support E-Switch mirroring and jump in one flow

mlx5 E-Switch mirroring is implemented as multiple destination array in
one steering table. The array currently supports only port ID as
destination actions.

This patch adds the jump action support to the array as one of
destination.
The packets can be mirrored to the port and jump to the next table in
the same destination array allowing to continue handling in the new
table.

For example:
    set sample_actions 0 port_id id 1 / end
    flow create 0 ingress transfer pattern eth / end actions
    sample ratio 1 index 0 / jump group 1 / end
    flow create 1 ingress transfer group 1 pattern eth / end actions
    set_mac_dst mac_addr 00:aa:bb:cc:dd:ee / port_id id 2 / end

The flow results all the matched ingress packets are mirrored
to port id 1 and go to group 1. In the group 1, packets are modified
with the destination mac and sent to port id 2.
