In AutoSegment::_changeDepth(), correct invalidation of GCells.

* Bug: In Anabatic::AutoSegment::_changeDepth(), GCells under the segment
    must be invalidated in order for the density to be recomputed.
    But we were using GCell::invalidate() which is meant for the quad-tree
    and graphic system, so the density almost never updated in case of
    a layer change, leading to over-congested GCells in the top layers
    (110% !).
       Now we directly set the Invalidated flag.
