535723f414 Start making use of getBelPinsForCellPin API 
This replaces getNetinfoSinkWire with 3 new functions for different use
cases.

At the moment all existing code has been moved to getNetinfoSinkWire
with phys_idx=0 so the build doesn't break; but this won't yet function
properly with more than one sink. But it provides a base on which to
work on refactoring the routers to support this case.

85bb108ba4 Add getBelPinsForCellPin to Arch API 
This is a basic implementation, without considering "M of N"
arrangements (e.g. for LUT permuation where you only want to route to 1
out of 4/6 sinks) or using a type other than IdString to identify bel
pins.

But this is also enough to start working out where in nextpnr will break
due to removing the 1:1 cell:bel pin cardinality, as a next step.
