lef: Fixing VNB/VPB properties in .magic.lef files.

Both the `PIN VNB` and `PIN VPB` are now marked with `DIRECTION INOUT`. The `PIN VNB` is marked with `USE GROUND` and the `PIN VPB` is marked with `USE POWER`. This should fix the `.magic.lef` file usage with OpenROAD (and hopefully other tools too). Fixes google/skywater-pdk#172 Signed-off-by: Tim 'mithro' Ansell <tansell@google.com>
