Gowin. BUGFIX Use a separate net for segment gates (#1470)
* Gowin. BUGFIX Use a separate net for segment gates

We use a temporary separate small network (typically 2 - 3 sinks) for
routing from the segment network source to the segment gate. This fixes
the rare but unpleasant case of self-intersection when a route to a gate
is routed using PIPs after the gate, this is no longer allowed when
using a separate small network.
