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.

a8a27299ae Add pure-virtual ArchAPI interface 
This splits out the pure-virtual definition of the architecture API into
ArchAPI; leaving BaseArch to only provide default implementations (which
can now be completely opted out of by deriving from ArchAPI instead of
BaseArch).

8f76af40db nextpnr: Add base virtual functions for non-range Arch API 
This makes the Arch API clearer and also allows a base implementation of
functions to reduce the amount of complexity to get a basic Arch up and
running.

Currently this only implements these for functions that don't return a
range. Range-returning functions will require more work in order due to
the current 'duck typing' approach (probably a struct that contains the
range types combined with templating.)
