Issue created by <https://github.com/kareefardi|kareefardi>
It was assumed that using def/lef will blackbox standard cells and create a spice view of the layout with blackboxed standard cells and hence run abstract LVS. Upon investigation, it turns out that magic spice extraction depends on `MAGTYPE` whether its `maglef` or `mag`. This issue proposes integrating this to openlane2.
