add support for JSON config

[vvbandeira]

OpenLane now uses JSON to set configs instead of tcl files.

Enable back:

 //'mpw7_microwatt mpw7_Microwatt_FP_DFFRFile',//json format
 //'mpw7_microwatt mpw7_Microwatt_multiply_add',//json format

@vvbandeira, is there any plan on getting the OpenLane-MPW-CI working again or is this considered dead ?

Effectively dead. What's your interest?

I don't think it has run for a long time (@vvbandeira am I mistaken?). In any case, why the interest?

I was looking for the (x86 ?) macOS compile logs that I remember to have seen, saw that the macOS check-in built was disabled (why ?), found the GitHub CI project linked from the OR projects, saw that it passed til a year and a half ago and was wondering why it was abandoned…

PII is no longer involved in the MPW program (nor does it exist outside of chip ignite). Mac was never supported and our only CI machine failed.
