Zone filler: pads non connected in zone option: use same algo as the 5.1 branch 

to calculate thermal clearance (antipad size) for pads having the same netcode
as the zone, the net clearance has no meaning
(net clearance between object of the same net is 0)
and the zone_clearance can be set to 0 (i.e. use the netclass clearance).
Therefore use the antipad clearance (thermal clearance) or the zone_clearance if bigger.
