net: bridge: vlan: use br_rports_fill_info() to export mcast router ports

Browse Source 
Embed the standard multicast router port export by br_rports_fill_info()
into a new global vlan attribute BRIDGE_VLANDB_GOPTS_MCAST_ROUTER_PORTS.
In order to have the same format for the global bridge mcast context and
the per-vlan mcast context we need a double-nesting:
 - BRIDGE_VLANDB_GOPTS_MCAST_ROUTER_PORTS
   - MDBA_ROUTER

Currently we don't compare router lists, if any router port exists in
the bridge mcast contexts we consider their option sets as different and
export them separately.

In addition we export the router port vlan id when dumping similar to
the router port notification format.
