feat: add support for GF180 and SKY130 PDKs with corresponding warnings and simulation files

- Introduced new JSON files for warnings generated by Icarus Verilog, Verilator, and Yosys for both GF180 and SKY130 PDKs.
- Updated the build requirements to include necessary packages for handling JSON data.
- Modified RTL filelists to use generated files for GF180 and SKY130 standard-cell models.
- Enhanced the Iverilog makefile to generate filelists dynamically based on the selected PDK.
- Implemented a Python script to generate Iverilog filelists, accommodating both GF180 and SKY130 technologies.
- Added behavioral definitions for GF180 UDPs and a tri-state buffer for netlist simulations.
- Updated Yosys synthesis scripts to handle new PDKs and ensure proper tie cell mapping.
- Extended regression scripts to support PDK-specific commands for GF180 and SKY130.
- Added tests to verify that PDK-specific regression commands cover firmware, RTL, and netlist simulations.
