[PR #11182/76589bd9 backport][stable-12] nmcli: allow VxLan multicast and bridge port (#11251)

nmcli: allow VxLan multicast and bridge port (#11182)

VxLan virtual devices can be added to bridge ports, like any other
devices. And when using multicast remote addresses,
NetworkManager need to know the parent device as well.


(cherry picked from commit 76589bd97a)
