OpenRAM Add ROM config for gf180mcu

Since OpenROM has experimental support for gf180mcuD, I think it would be useful to have a test to make sure it does not break in the future.

This PR adds one config for: gf180mcu_rom_1kbyte.

For now, I disabled check_lvsdrc for gf180mcu as it seems the magic version installed via conda is too old. Maybe the tools/PDK versions that OpenRAM uses can be updated in the future.

Also, when writing rom_data, it makes sure that the output directory exists.

I created the variable lef_rom_interconnect to specify the metal layers for lef writing. Maybe you know a better name for it ;)

It seems some regressions broke, so it's in dev but not stable yet.

Oh no! From what I can remember, it worked for me locally. Please let me know if I can help.
