Development planning, Milestone 3

[mike-lischke]

This list covers the next steps after having both a full TS runtime and the full runtime/api tests ported to TS.

• Consolidate the TS runtime (consistent naming of properties, remove leading underscores in properties, really make private what is private, convert data-only classes to interfaces etc.).
• Optimize the runtime to get it as close as possible to the old JS runtime execution speed.
• Do initial port of the Java ANTLR4 tool to TS and make it build.
• Get the TS tool port to work properly.
• Release the tool as node package.

The first two steps are handled in an own branch, which later gets released as a new major version (because of API changes).

🎉 The optimized antlr4ng runtime performs really well. It's faster in most aspects than any of the other TS/JS runtimes (antlr4, antlr4ts, antlr4wasm).
