Bastian Koppelmann 9749c522d1 tech: Make power_grid configurable
this is the first step to allow engineers, porting technologies, more room
for routing their handmade cells.

For now, we don't allow the specification of power_grids where the lower layer
prefers to be routed vertically. This is due to the router not
connecting some pins properly in that case.
