{nl,mac}80211: add dot11MeshConnectedToMeshGate to meshconf

Browse Source 
When userspace is controlling mesh routing, it may have better
knowledge about whether a mesh STA is connected to a mesh
gate than the kernel mpath table.  Add dot11MeshConnectedToMeshGate
to the mesh config so that such applications can explicitly
signal that a mesh STA is connected to a gate, which will then
be advertised in the beacon.
