coremodels: Automatically generate coremodel registries (#50057)

* coremodel: Generate static registry

* Actually make codegen work

Also, remove the per-coremodel assignability test from generator set.

* Make wire gen depend on cue gen

This is necessary now that we're generating a wire set as part of
coremodel registry generation.

* Add wire inject bits to http server

* s/staticregistry/registry/

* move to static and dynamic wording

* Move registry type into registry package

* Use static registry in http handler

* Oi comments
