Add support for the SkyWater130 Caravel harness to "core2chip". 

It is now possible to automatically nest a core block inside a harness
frame, like we do for an ordinary chip whith I/O pads. The DEF harness
file "user_project_wrapper.def" must be made available though the block
configuration variable:
   conf.cfg.harness.path = './user_project_wrapper.def'
A first small example is given in:
   alliance-check-toolkit/benchs/counter/sky130_c4m
The harness layout is stripped from it's native power grid (but keep
the power ring). I/O pad information in block/configuration is
slightly "bent* to manage pins instead of complete I/O pads.

* Bug: In cumulus/plugins.block.Block.setupAb(), the routingBb was not
    set up when working in chip mode. Now set (to the corona AB).
* Change: In cumulus/plugins.chip.__init__, move there the CoreWire
    class (from chip/pads.py) so it can be shared with the harness
    version of pads.py.
* Change: In cumulus/plugins.chip.powerplane, compute the intersection
    between the vertical supply stripes and the deep horizontal power
    lines in a smarter fashion, so two (or more) vertically contiguous
    BigVias are merged into one (two BigVia side by side where causing
    mimimal spacing distance violation on the cut in Sky130).

connecting to I/O external pads or the harness pins.
2. At the corona level, *outside* the corona abutment box, so
they overlap with the part draw at chip level, as we know the
placement of the corona inside the chip.
This part of the wires are *on grid*. And they may also be
symbolic if the corona+core is in symbolic layout. This just
on the outside of the corona that we make the transition
between the real outer chip and the internal symbolic core.
In the case a complete chip with I/O pad, we can also request the
insertion of a jumper to protect against antenna effect. This is
not working yet in the case of a harness.
