Migrate Build System to Match OpenLane 2 (The-OpenROAD-Project#2115)
+ Repository is now a Nix flake ~ Change all invocations of `openroad -python` to use `run_odbpy_script` for consistency ~ Change build system from ad-hoc to Nix, still producing a Docker image as a final result ~ Update KLayout scripts to use `klayout-pymod` or properly parse commandline arguments ~ `open_pdks` -> `bdc9412` to match OpenLane 2 - Remove local installer; `nix run .` will run OpenLane natively
