bridge: Add internal flags for per-{Port, VLAN} neighbor suppression

Browse source 
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.
