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.)

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.

235a8e07e3 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).

6d23461bcd ecp5: Proof-of-concept using IdStringList for bel names 
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.
