bridge: Add internal flags for per-{Port, VLAN} neighbor suppression
Add two internal flags that will be used to enable / disable per-{Port, VLAN} neighbor suppression: 1. 'BR_NEIGH_VLAN_SUPPRESS': A per-port flag used to indicate that per-{Port, VLAN} neighbor suppression is enabled on the bridge port. When set, 'BR_NEIGH_SUPPRESS' has no effect. 2. 'BR_VLFLAG_NEIGH_SUPPRESS_ENABLED': A per-VLAN flag used to indicate that neighbor suppression is enabled on the given VLAN.
