designs: ihp-sg13g2: Add I2C GPIO Expander

Simple I2C GPIO expander with 8 GPIO pins. This design is a full chip layout with IO ring included. It's missing metal fill and therefore not tape-out ready but a new example to demonstrate OpenROAD and/or the IHP PDK due it's short build time. Signed-off-by: Daniel Schultz <[email protected]>
