[v1 2/2] app/testpmd: introduce VXLAN-GBP and VXLAN-GPE fields

After unification of VXLAN and all its extension protocols(VXLAN-GPE and
VXLAN-GBP currently), all related RTE items should be spicified after
'vxlan'. And it's user's responsibility to specify correct UDP port for
the protocol to be matched.

Below are the examples to match standard VXLAN, VXLAN-GPE and VXLAN-GBP.
To match standard vxlan,
... / udp dst is 4789 / vxlan ... / ...
To match VXLAN-GBP group policy ID 4321,
... / udp dst is 4789 / vxlan group_policy_id is 4321 ... / ...
To match VXLAN-GPE,
... / udp dst is 4790 / vxlan protocol is 2 ... / ...
