Klas Nordmark 8d760d2666 Added Openlane support with CI 
As part of my and Olof Kindgrens work on adding Openlane support to Edalize,
we've noticed that a lot of the examples in the Openlane repository are from
other known sources and we would prefer to upstream when possible.

This commit adds a tcl file with parameters for Openlane, a sky130
target using Openlane in the core, and a github action for building it on push.
