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.

Arches might otherwise have range types named ambigiously with the entry
in ArchRanges.

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).

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.)

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.

This avoids storing the entire pip to wire map in memory with a moderate
runtime increase and a dramatic memory decrease (2 GB to 200 MB for
A50T).

This is a complete implementation of IdStringList for ECP5; excluding
the GUI (which you will have to disable for it to build).

This uses the new IdStringList API to store bel names for the ECP5. Note
that other arches and the GUI do not yet build with this
proof-of-concept patch.
getBelByName still uses the old implementation and could be more
efficiently implemented with further development.

The bba approach seems widely used enough that it's reasonable for this
