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.

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.)

- Change non-Arch methods to snake_case
- Adds some utility functions to for accessing bel_data.

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.

Use a LRU cache for pip to wire map.

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 makes the difference clearer between the general arch API that
everyone must implement; and helper functions specific to one arch.
