net/mlx5: support E-Switch manager egress traffic match

For egress packet on representor, the vport ID in transport domain
is E-Switch manager vport ID since representor shares resources of
E-Switch manager. E-Switch manager vport ID and Tx queue internal device
index are used to match representor egress packet.

This patch adds flow item port ID match on E-Switch manager.

E-Switch manager vport ID is 0xfffe on BlueField, 0 otherwise.
