This adds structures for DeviceResources for the default values for cell
pins that are missing or disconnected.
Previously the contract was that the synthesis tool would always give
cell pins a value, but this has several problems:
- existing flows aren't doing this
- cells might want to be created by the PnR tool or anything else
reading the interchange format
- sometimes, floating is a valid default value (for example certain
dedicated pins) and the existing contract didn't recognise that
- setting all disconnected pins to ground is definitely not correct,
vendor tools usually connect disconnected clock enables to Vcc for
example.
