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.

c7ef7e1902 generic: Base upon ArchAPI 
As generic is often picked as our 'odd-one-out' we also use it as an
example of an Arch that does not build upon BaseArch.

c99fbde0eb Mark IdString and IdStringList single argument constructors explicit. 
Single argument constructors will silently convert to that type.  This
is typically not the right thing to do.  For example, the nexus and
ice40 arch_pybindings.h files were incorrectly parsing bel name strings,
etc.

b18ea204c2 Remove wire alias API 
It has not actually been implemented in any router for over 2.5 years and causes nothing more than confusion. It can always be added back if it forms part of a future solution; possibly as part of a more general database structure rethink.
