Remove unused "CLIP_..." registers Make generate-memory-mapmaking check all type strings are explicitly defined. Simplify string interpolation of types. Update existing type strings. Add type strings for Rust. Remove "TODO D" as many other languages are missing, and adding support for its naming convention would complicate this script.
