Convert the utils/tty RBI generator to a Tapioca compiler

- The preferred way of doing RBI generation is via Tapioca. So I am
  trying to stop being intimidated by it, by learning how it works.
- This is very WIP still, currently failing with the following message
  because the `module` name is missing in the generated RBI file.

```
There are parse errors in the generated RBI files.

Errors:
  sorbet/rbi/dsl/tty.rbi:8: unexpected token tNL (2001)
  sorbet/rbi/dsl/tty.rbi:64: unexpected token "end" (2001)
```
