Summary:
Ref T8726. I'm primarily trying to modularize tokenizer values so we don't have to update JS to add a new one.
This is ultimately the blocker for "select" custom fields working in Herald.
This inches us toward that. I'm //not// modularizing conditions or control types in this round, but hope to end up with hard-coded conditions (which are highly general and very rarely change), hard-coded control types (which are also highly general and very rarely change) and completely modular fields and values (which have mid-to-low generality and change frequently).
Test Plan: Used UI to interact with "none", "text", and new-style "select" controls. No actual support for tokenizers yet.
