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.

6bd3dba1e3 Remove the unused CellInfo::pins field 
No arches ever actually used this to implement a Cell->Bel pin mapping,
and in practice if any did try they would inevitably hit bitrot.

This field had limited use in practice as it is necessary to also
support cases where one cell pin maps to more than one bel pin. Removing
this old field is the first step towards developing a new API for this.
